All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
We have already issued many Fataawa about the invalidity of the misconceptions that the enemies of Islam are propagating about the equality of men and women, and rejecting their claim that women can lead men in prayer or make the call to the prayer or stand in the same row with men. We mentioned the ruling about these issues, so please refer to Fataawa: 89729, 88708 and 82591.
As regards the issue of women entering the mosque from the main entrance and whether there is any evidence that prohibits them from doing so, the answer is that there is no evidence that prohibits them from doing so if entering from this entrance does not make them mix with men. However, the Prophet used to urge the companions to make a special door for women and encouraged them to be separate and far from each other. Ibn 'Umar narrated: "The Prophet said: ''It is better if we leave this door for women." Naafi' said: "Ibn 'Umar never entered using that door until he died." [Abu Daawood]
You should know, dear brother, that it is Islam that gave the woman her complete right, and honoured her as a mother, a sister, a daughter, a wife, and as an aunt; and she is not despised as the enemies of Islam claim. Indeed, I swear by Allaah, that it is they who despised the woman and turned her into a cheap product from whom they take pleasure as they wish and then discard her. The true state of affairs and their behaviour with their mothers, wives, daughters and sisters is the best evidence about the wrong that they are doing to them by their lack of respect, caring for them, protecting their chastity, supporting their children, as well as incest.
By referring to the above-mentioned Fataawa, you will indeed find that which would convince anyone who has the slightest sound mind, Inshaa' Allaah.
Allaah knows best.
