Umm Sulaim Al Rumaisa said “The Prophetﷺ slept and awoke while she was washing her head.” He awoke laughing. She asked “Apostle of Allaahﷺ are you laughing at my head?” He replied, No. She then narrated the rest of the tradition enlarging and reducing.
Abu Dawud said:
Al-Rumaisa was the foster sister of Umm Sulaim.
حَدَّثَنَا يَحْيَى بْنُ مَعِينٍ، حَدَّثَنَا هِشَامُ بْنُ يُوسُفَ، عَنْ مَعْمَرٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أُخْتِ أُمِّ سُلَيْمٍ الرُّمَيْصَاءِ، قَالَتْ نَامَ النَّبِيُّ ﷺ فَاسْتَيْقَظَ وَكَانَتْ تَغْسِلُ رَأْسَهَا فَاسْتَيْقَظَ وَهُوَ يَضْحَكُ فَقَالَتْ يَا رَسُولَ اللَّهِ أَتَضْحَكُ مِنْ رَأْسِي قَالَ
" لاَ " . وَسَاقَ هَذَا الْخَبَرَ يَزِيدُ وَيَنْقُصُ .
