حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا مَالِكٌ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ زَيْنَبَ بِنْتِ أَبِي سَلَمَةَ، عَنْ أُمِّ سَلَمَةَ أُمِّ الْمُؤْمِنِينَ، أَنَّهَا قَالَتْ جَاءَتْ أُمُّ سُلَيْمٍ امْرَأَةُ أَبِي طَلْحَةَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَتْ يَا رَسُولَ اللَّهِ، إِنَّ اللَّهَ لاَ يَسْتَحْيِي مِنَ الْحَقِّ، هَلْ عَلَى الْمَرْأَةِ مِنْ غُسْلٍ إِذَا هِيَ احْتَلَمَتْ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏‏‏.‏ "‏ نَعَمْ إِذَا رَأَتِ الْمَاءَ ‏"
