Purification

‘Imrān ibn Husayn (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) saw a person sitting aloof and not praying with the people. He asked him: "O so and so, what prevented you from offering the prayer with the people?" He replied: "O Messenger of Allah, I am ritually impure and there is no water." In response, the Prophet (may Allah’s peace and blessings be upon him) said: "You should use clean earth, and that will be sufficient for you."

‘Ammār ibn Yāsir (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) sent me on an errand, and I became Junub (in a state of major ritual impurity) and could not find water. So, I rolled in the dirt like an animal and then came to the Prophet (may Allah's peace and blessings be upon him) and told him about it. He said, "It was sufficient for you to do this with your hands." Then, he struck the ground once with his hands, then wiped the right hand with the left one, the back side of his hands and his face.

Jābir ibn ‘Abdullah (may Allah be pleased with him and his father) reported that the Prophet (may Allah's peace and blessings be upon him) said: "I was granted five that none before me was granted: I was granted victory through terror from a distance of one month's journey; the earth has been made for me a mosque and a means of purification, so any man from my Ummah who is caught up by the prayer should pray; the spoils of war have been made lawful for me, although they were not lawful for anyone before me; I have been granted the intercession; and a prophet used to be sent to his people in specific, whereas I have been sent to all people."
