Ikrama عكرمة · The Book of Purification and its Sunnah

"Whenever the Prophet went to relieve himself, he would go far away."

The Messenger of Allah forbade urinating into standing water.

"I saw the Messenger of Allah performing ablution, and he wiped his head once."

The Messenger of Allah performed ablution and he wiped his head and his ears, inside and out.

When it was the year of the Conquest (of Makkah), the Messenger of Allah got up to perform a bath and Fatimah screened him. Then he took his garment and wrapped himself in it (such that it became like the towel used to dry oneself).

"The Prophet used to bring his head close to me when I was menstruaring and he was in I'tikaf (seclusion in a mosques for the purpose of worship), and I would wash it and comb his hair."

"The Messenger of Allah saw a man performing ablution and he missed a spot the size of a fingernail on his foot. He commanded him to repeat the ablution and his prayer, so he did."
