the Messenger of Allah (ﷺ) used to pray while. I was by his side in the state of menstruation. Sometime his cloth would touch me when he prostrated. He would pray on a small mat.
Sunan Abi Dawud Book 2, Hadith 266
← Previous Hadith when any of you prays and takes off his sandals, he should not harm anyone by them. He should place them between his feet or pray with them on

Sunan Abi Dawud Book 2, Hadith 265 Next Hadith → A man from the Ansar said: I am a corpulent man-and he was (actually) a fat man; I cannot pray along with you. He prepared food for him and invited him to his house. (he said) (please) pray (here) so that I may see how you pray, and then I would follow you. They (the people) washed one side of their mat. He (the prophet) then got up and prayed two Rak’ahs. Ibn al-Jarud asked Anas b. Malik: would he (the prophet) say the forenoon prayer? He replied: I did not see him offering this prayer except that day.
