Abu al-Zanad أبو الزناد · The Book of Purification and its Sunnah

She and the Messenger of Allah used to take a bath from a single vessel.

"Men and women used to perform ablution from a single vessel during the time of the Messenger of Allah."

"The Messenger of Allah said: 'Jibril taught me (how to perform) the ablution, and he ordered me to sprinkle water underneath my garment, lest a drop of urine leak out after the ablution.'" (Da'if) Other chains with similar wording.

The Messenger of Allah performed ablution, then he turned inside out the woolen garment that he was wearing and wiped his face with it.

Mahmud bin Rabi' remembered that the Prophet spat into a bucket from a well that belonged to them.

A man came to the Prophet; he had performed ablution and has missed a spot the size of a fingernail where water had not reached. The Prophet said to him: 'Go back and perform ablution properly.'"
