Abdur Rahman bin Ibrahim عبد الرحمن بن إبراهيم - دحيم · The Book of Purification and its Sunnah

"The Messenger of Allah forbade us from facing either of the two Qiblah when defecating or urinating."

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

The Messenger of Allah performed ablution and wiped over his socks and his sandals.

"Aishah dropped a necklace and stayed behind to look for it. Abu Bakr went to 'Aishah and got angry with her for keeping the people waiting. Then Allah revealed the concession allowing dry ablution, so we wiped our arms up to the shoulders. Abu Bakr went to 'Aishah and said: 'I did not know that you are blessed.'"

"The Messenger of Allah said: 'Under every hair there is the state of sexual impurity, so wash the hair and cleanse the skin.'"
