The Prohibition Of Preventing Women From Going To The Masjid
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا اسْتَأْذَنَتِ امْرَأَةُ أَحَدِكُمْ إِلَى الْمَسْجِدِ فَلاَ يَمْنَعْهَا .
It was narrated from Salim that his father said: "The Messenger of Allah (ﷺ) said: 'When the wife of any one of you asks for permission to go to the Masjid, do not stop her.'"
