Anas bin Malik (RA) reported that his grandmother, Mulaikah, invited the Messenger of Allah ﷺ to a dinner which she had prepared. He (the Holy Prophet) ate out of that and then said: Stand up so that I should observe prayer (in order to bless) you. Anas bin Malik (RA) 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 rakahs of prayer and then went back.
