أَخْبَرَنَا سَعِيدُ بْنُ يَحْيَى بْنِ سَعِيدٍ الْأُمَوِيُّ، ‏‏‏‏‏‏قال:‏‏‏‏ حَدَّثَنَا أَبِي، ‏‏‏‏‏‏قال:‏‏‏‏ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، ‏‏‏‏‏‏عَنْ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ أَبِي طَلْحَةَ، ‏‏‏‏‏‏عَنْ أَنَسِ بْنِ مَالِكٍ، ‏‏‏‏‏‏أَنَّ أُمَّ سُلَيْمٍ سَأَلَتْ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ يَأْتِيَهَا فَيُصَلِّيَ فِي بَيْتِهَا فَتَتَّخِذَهُ مُصَلًّى، ‏‏‏‏‏‏ فَأَتَاهَا فَعَمِدَتْ إِلَى حَصِيرٍ فَنَضَحَتْهُ بِمَاءٍ، ‏‏‏‏‏‏فَصَلَّى عَلَيْهِ وَصَلَّوْا مَعَهُ .

It was narrated from Anas bin Malik that Umm Sulaim asked the Messenger of Allah (ﷺ) to come to her and pray in her house so that she could take (the place where he prayed) as a Musalla (prayer place). So he came to her and she went and got a reed mat and sprinkled it with water, and he prayed on it, and they prayed with him.
