Anas bin Malik reported,

Anas bin Malik reported that his grandmother Mulaykah invited the Messenger of Allah ﷺ to a meal she had prepared. He ate some of it and then said, "Get up, and I will lead you in prayer."Anas bin Malik said, "I went over to a mat of ours that had turned black from long use, and I sprinkled it with water. The Messenger of Allah ﷺ stood on it, and I and the orphan boy lined up behind him, with the old woman behind us. The Messenger of Allah ﷺ led us in two units of prayer, then he left."

عن أنس بن مالك

أن جدته مليكة دعت رسول الله ﷺ لطعام صنعته فأكل منه ثم قال قوموا فأصلي لكم قال أنس بن مالك فقمت إلى حصير لنا قد اسود من طول ما لبس فنضحته بماء فقام عليه رسول الله ﷺ وصففت أنا واليتيم وراءه والعجوز من ورائنا فصلى لنا رسول الله ﷺ ركعتين ثم انصرف
