Umm Sulaym asked the Messenger of Allah ﷺ to come to her home and pray there so she could take that spot as a place of prayer. He came to her, and she brought out a mat and sprinkled it with water. He prayed on it, and they prayed along with him.

أن أم سليم سألت رسول الله ﷺ أن يأتيها فيصلي في بيتها فتتخذه مصلى فأتاها فعمدت إلى حصير فنضحته بماء فصلى عليه وصلوا معه
