Abu Umama bin Sahl · The Book of Purification and its Sunnah

"I see that your companion (the Prophet) is teaching you everything, even how to relieve yourselves?" He said: "Yes indeed. He has ordered us not to face the Qiblah (prayer direction) nor to clean ourselves with our right hands, and not to be content with anything less than three stones, which are not to include any excrement or bones."

'The Messenger of Allah said: 'When you get up for prayer, perform ablution properly and make the water run between your toes and your fingers.'"

"The Messenger of Allah said: 'If you drink milk, then rinse your mouths, for there is some greasiness in it.'"

The Prophet was asked about the water basins located between Makkah and Al-Madinah, which were visited by wild animals, dogs and donkeys, and about using them for means of purification. He said: "Whatever they (the animals) have carried in their bellies is for them, and whatever is left over is for us, and is pure."

They asked 'Abdullah bin Abi Awfa about dry ablution. He said: "The Prophet commanded 'Ammar to do like this;' and he struck the ground with his palms, shook the dust off and wiped his face. (Da'if)Hakam said, "and his hands," Salamah said, "and his elbows."
