Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated: When the verse of tayammum was revealed, I did not know how I should perform it. So I went to the house of the Messenger of Allah (peace and blessings be upon him) to present myself to him, but I did not find him. It was said: The Messenger of Allah (peace and blessings be upon him) has gone outside. I knew the path where I could find him, so I followed behind him. I think he sensed my need, so he stood up, then struck both his hands on the earth, wiped his face and hands, and did not add anything to that. I returned and did not ask him (about the method of tayammum).
