All praises be to Allaah, Lord and Sustainer of the worlds, and may the peace and blessings of Allaah be upon our Prophet Muhammad (peace be upon him) and upon his family and companions.
All the commands and prohibitions in Islaam are equal for both men and women umless clearly specified by the Shari’ah
Therefore there can be no difference in the prayer of a man and a lady.
The Messenger of Allaah (peace and blessings of Allaah be upon him) said:
“ Pray as you see me praying ” agreed upon.
This command is general without any distinction between men and womem, that’s why there is no difference between the Salat of a lady and a man. Both have to pray in the manner the Prophet of Allaah (peace and blessings of Allaah be upon him) prayed except, where Allaah or the Messanger of Allaah (peace and blessings of Allaah be upon him) have specifically commanded otherwise, such as the awraah of a lady being different from a man, or her not raising her voice in the presence of non-mahram men or her prayer being preferred in her house and praying in congregation not being obligatory on her. All this is because of specific statements from the Messanger of Allaah (peace and blessings of Allaah be upon him) on these issues.
But as for as her standing, raising her arms and saying takbeer, placing her right hand over left on her chest during recitation, bowing, prostrating and sitting etc are concerned, there is no authentic text from the Messanger of Allaah (peace and blessings of Allaah be upon him) which differentiate between a man and a woman.
That’s why Muslim women are to perform the Salaat in the same manner as men unless specified otherwise in the Shari’ah.
And Allah the Most Knowledgeable knows what is best and most correct.
May Allaah help and guide us to do all that He is pleased with and his Peace and blessings be upon His last Prophet Muhammad.
