Stand up so that I should observe prayer (in order to bless) you Anas b. Malik said: I stood up on a mat (belonging to us) which had turned dark on account of its long use. I sprinkled water over it (in order to soften it), and the Messenger of Allah (ﷺ) stood upon it, and I and an orphan formed a row behind him (the Holy Prophet) and the old woman was behind us, and the Messenger of Allah (ﷺ) led us in two rak'ahs of prayer and then went back.

Anas b. Malik reported that the Messenger of Allah (ﷺ) wits the best among people in character. On occasions, the time of prayer would come while he was in our house. He would then order to spread the mat lying under him. That was dusted and then water was sprinkled over it. The Messenger of Allah (ﷺ) then led the prayer and we stood behind him, and that mat was made of the leaves of date-palm.

The Apostle of Allah (ﷺ) came to us and there was none in our house but I, my mother and my aunt Umm Haram. He (the Holy Prophet) said: Stand up so that I may lead you in prayer (and there was no time for prescribed prayer). He led us in prayer. A person said to Thabit: Where stood Anas with him (the Holy Prophet)? He replied: He was on the right side. He then blessed us, the members of the household with every good of this world and of the Hereafter. My mother said: Messenger of Allah (and then, pointing towards Anas, said), here is your little servant, invoke the blessing of Allah upon him too. He then blessed me with every good, and he concluded his blessings for me (with these words): Allah! increase his wealth, and his children and make (them the source of) blessing for him.

Abu Sa'id al-Khudri reported that he went to the Messenger of Allah (ﷺ) and found him observing prayer on a mat and prostrating on that.
