(43) باب الصَّلاَةِ عَلَى الْحَصِيرِ
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.
