Muwatta Imam Malik Book of The Qibla, Hadith 12

Yahya related to me from Malik that he had heard that Abdullah ibn Umar said, "The Messenger of Allah ﷺ said, 'Do not forbid the female slaves of Allah from (going into) the mosques of Allah.' "

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " لاَ تَمْنَعُوا إِمَاءَ اللَّهِ مَسَاجِدَ اللَّهِ " .
