"Lucifer" "Shayton" "Belzebub" "Satan"
No matter what name you call him, he is still the devil and he is full of evil.

But still, we want to know.. "Why is the Devil Called Shayton?

In the Arabic language, shayton or shaytan is derived from shatana, which means the far thing.
So, this implies the devil or shayton has a very different nature from us humans (provided we are believing in Allah and trying to do righteousness) and his sinful nature and ways are far away from all righteousness.

It was also said that Shaytan is derived from shata, (literally `burned'), because it was created from a smokeless fire. Some scholars said that both meanings are correct, although they state that the first meaning is more plausible.

Further, Siybawayh (the renowned Arab linguistic) said, "The Arabs say, `So-and-so has Tashaytan,' when he commits the act of the devils. If Shaytan was derived from shata, they would have said, Tashayyata (rather than Tashaytan).''

Hence, shaytan is derived from the word that means, far away. This is why they call those who are rebellious (or mischievous) from among the Jinns and mankind a 'shaytan'.

Allah said in surah An-Aam:

"And so We (whenever Allah uses the term "We" it is in the Royal sense as when a king or queen might say, "We decree the following decree" - not as a plural) have appointed for every Prophet enemies; shayatin (devils) among mankind and Jinn, inspiring one another with adorned speech as a delusion (or by way of deception)."
(6:112)

The Meaning of Ar-Rajim

Ar-Rajim means, being expelled from all types of righteousness. Allah said:

"And indeed We have adorned the nearest heaven with lamps, and We have made such lamps Rujuman (as missiles) to drive away the Shayatin (devils)."
(67:5)

Allah also said:

"Verily, We have adorned the near heaven with the stars (for beauty). And to guard against every rebellious devil. They cannot listen to the higher group (angels) for they are pelted from every side. Outcast, and theirs is a constant (or painful) torment. Except such as snatch away something by stealing, and they are pursued by a flaming fire of piercing brightness."
(37:6-10)

Further, Allah said:

"And indeed, We have put the big stars in the heaven and We beautified it for the beholders. And We have guarded it (near heaven) from every Shaytan Rajim (outcast Shaytan). Except him (devil) who steals the hearing then he is pursued by a clear flaming fire."
(15:16-18).

There are several similar verses.

It was also said that rajim means, the person who throws or bombards things, because the devil throws doubts and evil thoughts in people's hearts. The first meaning is more popular and accurate.

Al Isti'adhah - What does isti'adhah mean?

Isti'adhah means: "I seek refuge with Allah from the cursed Satan so that he is prevented from affecting my religious or worldly affairs, or hindering me from adhering to what I was commanded, or luring me into what I was prohibited from.''

Indeed, only Allah is able to prevent the evil of Satan from touching the son of Adam. This is why Allah allowed us to be lenient and kind with the human devil, so that his soft nature might cause him to refrain from the evil he is indulging in. However, Allah required us to seek refuge with Him from the evil of Satan, because he neither accepts bribes nor does kindness affect him, for he is pure evil. Thus, only He Who created Satan is able to stop his evil. This meaning is reiterated in only three Ayat in the Qur'an. Allah said in Surat Al-A`raf:

"Show forgiveness, enjoin what is good, and turn away from the foolish (i.e.; don't punish them." (9:199)

This is about dealing with human beings. He then said in the same surah:

"And if an evil whisper comes to you from Shaytan, then seek refuge with Allah. Verily, He is Hearing, Knowing."
(7: 200)

Allah also said in Surat Al-Mu'minun:

"Repel evil with that which is better. We are Best-Acquainted with the things they utter.
And say: "My Lord! I seek refuge with You from the whisperings (suggestions) of the Shayatin (devils). And I seek refuge with You, My Lord! lest they should come near me.''
(23:96-98)

Further, Allah said in Surat As-Sajdah

"The good deed and the evil deed cannot be equal. Repel (the evil) with one which is better, then verily he, between whom and you there was enmity, (will become) as though he was a close friend. But none is granted it (the above quality) except those who are patient ? and none is granted it except the owner of the great portion (of happiness in the Hereafter, i.e. Paradise and of a high moral character) in this world. And if an evil whisper from Shaytan tries to turn you away (from doing good), then seek refuge in Allah. Verily, He is the Hearing, the Knowing"
(41:34-36)

The Tafsir (explanation) of isti'adhah (seeking Refuge)

Allah said in surah Al-Araf

"Show forgiveness, enjoin what is good, and stay away from the foolish (i.e. don't punish them). And if an evil whisper comes to you from Shaytan (Satan), then seek refuge with Allah. Verily, He is Hearing, Knowing."
(7:199-200)

And also in surah Al Mu'mimun

"Repel evil with that which is better. We are Best-Acquainted with things they utter. And say: "My Lord! I seek refuge with You from the whisperings (suggestions) of the Shayatin (devils). And I seek refuge with You, My Lord! lest they should come near me.''
(23:96-98)

And then surah Al Fusilat:

"Repel (an evil) with one which is better, then verily he with whom there was enmity between you, (will become) as though he was a close friend. But none is granted it except those who are patient ? and none is granted it except the owner of the great portion (of happiness in the Hereafter, i.e. Paradise and of a high moral character) in this world. And if an evil whisper from Shaytan tries to turn you away (O Muhammad ) (from doing good), then seek refuge in Allah. Verily, He is the Hearing, the Knowing."
(41:34-36)

These are the only three verses carrying this meaning. Allah commanded us to be lenient human enemy, so that his soft nature might make him an ally and a supporter. He also commanded that we seek refuge from the satanic enemy, because the devil does not relent in his enmity if we treat him with kindness and leniency. The devil only seeks the destruction of the Son of Adam due to the vicious enmity and hatred he has always had towards man's father, Adam. Allah said:

"O Children of Adam! Let not Shaytan deceive you, as he got your parents [Adam and Hawwa' (Eve)] out of Paradise"
(7:27)

Then Allah said in surah Al Mala'ikah

"Certainly, shayton is an enemy to you, so treat him as an enemy. He only invites his hizb (followers) to become the dwellers of the Blazing Fire."
(35:6)

And in surah Al Kahf (the Cave):

"Will you then take him (Iblis) and his offspring as protectors and helpers rather than Me while they are enemies to you What an evil is the exchange for the Zalimun (polytheists, and wrongdoers, etc)".
(18:50)

The devil assured Adam that he wanted to advise him, but he was lying. Hence, how would he treat us after he had vowed:

"By Your might, then I will surely, mislead them all. Except Your chosen servants among them (i.e. faithful, obedient, true believers of Islamic Monotheism).''
(38:82-83)

Also, Allah said:

"So when you [want to] recite the Qur'an, seek refuge with Allah from Shaytan, the outcast (the cursed one). Verily, he has no power over those who believe and put their trust only in their Lord (Allah). His power is only over those who obey and follow him (Satan), and those who join partners with Him."
(16:98-100)

Seeking Refuge before reciting the Qur'an

Allah said:

"So when you [want to] recite the Qur'an, seek refuge with Allah from Shaytan, the outcast (the cursed one).) meaning, before you recite the Qur'an."

Similarly, Allah said:

"When you intend to offer As-Salah (the prayer), wash your faces and your hands (forearms)."
(5:6)

This is the of meaning, before you stand in prayer, as evident by the Hadiths that we mentioned. Imam Ahmad recorded that Abu Sa`id Al-Khudri said:

"When the Messenger of Allah would stand up in prayer at night, he would start his prayer with the Takbir (saying "Allahu Akbar''; Allah is Greater) and would then supplicate:
"All praise is due to You, O Allah, and also the thanks. Blessed be Your Name, Exalted be Your sovereignty, and there is no deity worthy of worship except You."
He would then say three times:
"There is no deity worthy of worship except Allah."
He would then say:
"I seek refuge with Allah, the Hearing, the Knowing, from the cursed Satan, from his coercion, lures to arrogance and poetry."

The four collectors of the Sunan recorded this Hadith, which At-Tirmidhi considered the most famous Hadith on this subject.

Abu Dawud and Ibn Majah recorded that Jubayr bin Mut`im said that his father said:

When the Messenger of Allah started the prayer, he said:
"Allahu Akbar!" three times; "Al Hamdulillah" (three times); "Al Hamdulilah (day and night)" (three times); "O Allah! I seek refuge with You from the cursed Satan, from his Hamz, Nafkh and Nafth."

'Amr said, "The Hamz means asphyxiation, the Nafkh means arrogance, and the Nafth means poetry.''

Also, Ibn Majah recorded that 'Ali bin Al-Mundhir said that Ibn Fudayl narrated that 'Ata' bin As-Sa'ib said that Abu 'Abdur-Rahman As-Sulami said that Ibn Mas`ud said that the Prophet said:

"O Allah! I seek refuge with You from the cursed devil, from his Hamz, Nafkh and Nafth."

He said:

"The Hamz means death, the Nafkh means arrogance, and the Nafth means poetry.''

Seeking Refuge with Allah when One is Angry

In his Musnad, Al-Hafiz Abu Ya`la Ahmad bin `Ali bin Al-Muthanna Al-Mawsili reported that Ubayy bin Ka`b said, "Two men disputed with each other in the presence of the Messenger of Allah and the nose of one of them became swollen because of extreme anger. The Messenger of Allah said:

"I know of some words that if he said them, what he feels will go away, 'I seek refuge with Allah from the cursed Satan.'"

An-Nasa'i also recorded this Hadith in his book, Al-Yawm wal-Laylah.

Al-Bukhari recorded that Sulayman bin Surad said:

Two men disputed in the presence of the Prophet while we were sitting with him. One of them was cursing the other fellow and his face turned red due to anger. The Prophet said:
"I know of a statement which if he said it, will make what he feels disappear, 'I seek refuge with Allah from the cursed Satan.'"
They said to the man:
"Do you not hear what the Messenger of Allah is saying?"
He (the man) said
"I am not insane."

Also, Muslim, Abu Dawud and An-Nasa'i recorded this Hadith.

There are many other Hadiths about seeking refuge with Allah. One can find this subject in the books on supplication and the virtues of righteous, good deeds.

Is the Isti'adhah (seeking Refuge) required?

The majority of the scholars state that reciting the Isti'adhah (in the prayer and when reciting the Qur'an) is recommended and not required, and therefore, not reciting it does not constitute a sin.

However, Ar-Razi recorded that `Ata' bin Abi Rabah said that the Isti`adhah is required in the prayer and when one reads the Qur'an. In support of `Ata's statement, Ar-Razi relied upon the apparent meaning of the Ayah:

"Then seek refuge."

He said that the Ayah contains a command that requires implementation. Also, the Prophet always said the Isti`adhah. In addition, the Isti`adhah wards off the evil of Satan, which is neccessary, the rule is that the means needed to implement a requirement of the religion is itself also required. And when one says, "I seek refuge with Allah from the cursed devil.'' Then this will suffice.

_________________________________________
Virtues of the Isti'adhah

The Isti'adhah cleanses the mouth from the foul speech that it has indulged in. It also purifies the mouth and prepares it to recite the speech of Allah. Further, the Isti`adhah entails seeking Allah's help and acknowledging His ability to do everything. The Isti`adhah also affirms the servant's meekness, weakness and inability to face the enemy of his inner evil, whom Allah alone, Who created this enemy, is able to repel and defeat. This enemy does not accept kindness, unlike the human enemy. There are three Ayat in the Qur'an that affirm this fact.

We should state here that the believers, whom the human enemies kill, become martyrs, while those who fall victim to the inner enemy - Satan - become bandits. Further, the believers who are defeated by the apparent enemy - disbelievers - gain a reward, while those defeated by the inner enemy earn a sin and become misguided. Since Satan sees man where man cannot see him, it is befitting that the believers seek refuge from Satan with Whom Satan cannot see. The Isti`adhah is a form of drawing closer to Allah and seeking refuge with Him from the evil of every evil creature.
