48) Chapter: Permissibility Of Observing Nafl (supererogatory) Prayer In Congregation And That Too On The Mat Or The Covering Cloth Or Any Other Thing Which Is Free From Filth And Rubbish

Anas b. Malik reported that his grandmother, Mulaika, 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 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.
