The Prohibition Of Preventing Women From Going To The Masjid
Sunan an-Nasai
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.'"
