al-Husain bin Dhakwan al-Mua'lam الحسين بن ذكوان المعلم المكتب · The Book of Purification

"Should I perform Wudu' after eating food that I see in the Book of Allah is permissible because fire has touched it?" Abu Hurairah gathered some pebbles and said: "I bear witness (as many times as) the number of these pebbles, that the Messenger of Allah (ﷺ) said: 'Perform Wudu' from that which has been touched by fire.'"

"I asked 'Aishah about how the Messenger of Allah (ﷺ) performed Ghusl from Janabah. She said: 'The Messenger of Allah (ﷺ) used to pour water onto his hands three times, then he would wash his private part, then he would wash his hands, then rinse his mouth and nose, then pour water onto his head three times, then pour water over the rest of his body.'"
