Muwatta Malik #473
The Qibla
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم
" لاَ تَمْنَعُوا إِمَاءَ اللَّهِ مَسَاجِدَ اللَّهِ " .
Yahya related to me from Malik that he had heard that Abdullah
ibn Umar said, "The Messenger of Allah, may Allah bless him and grant
him peace, said, 'Do not forbid the female slaves of Allah from (going
into) the mosques of Allah.' "
