Mishkat al-Masabih 4 Prayer كتاب الصلاة 477

وَعَنِ ابْنِ عُمَرَ قَالَ: قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا اسْتَأْذَنَتِ امْرَأَة أحدكُم إِلَى الْمَسْجِد فَلَا يمْنَعهَا»

Ibn ‘Umar reported God’s Messenger as saying, “When the wife of any of you asks permission to enter the mosque he must not prevent her.” (Bukhari and Muslim.)
