Sunan Ibn Majah, Hadith 957 ⓘ
It was narrated from Zainab bint Umm Salamah that her mother said that her bed was in front of the place where the Messenger of Allah prostrated.
حَدَّثَنَا بَكْرُ بْنُ خَلَفٍ، وَسُوَيْدُ بْنُ سَعِيدٍ، قَالاَ حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا خَالِدٌ الْحَذَّاءُ، عَنْ أَبِي قِلاَبَةَ، عَنْ زَيْنَبَ بِنْتِ أَبِي سَلَمَةَ، عَنْ أُمِّهَا، قَالَتْ كَانَ فِرَاشُهَا بِحِيَالِ مَسْجِدِ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ .
