Here are the sources I quoted in this video:
Sunan Abu Dawud 67—I heard that the people asked the Prophet of Allah: Water is brought for you from the well of Buda’ah. It is a well in which dead dogs, menstrual cloths and excrement of people are thrown. The Messenger of Allah replied: Verily water is pure and is not defiled by anything.
Sunan Ibn Majah 520—It was narrated that Jabir bin Abdullah said: “We came to a pond in which there was the carcass of a donkey, so we refrained from using the water until the Messenger of Allah came to us and said: ‘Water is not made impure by anything.’ Then we drank from it and gave it to our animals to drink, and we carried some with us.”
Sahih al-Bukhari 5782—Allah’s Messenger said, “If a fly falls in the vessel of any of you, let him dip all of it (into the vessel) and then throw it [i.e. the fly] away, for in one of its wings there is a disease and in the other there is healing (antidote for it) i.e. the treatment for that disease.”
Musnad Ahmad 16245—[Mua’wiya said]: I saw the prophet sucking on the tongue or the lips of Al-Hassan son of Ali, may the prayers of Allah be upon him. For no tongue or lips that the prophet sucked on will be tormented (by hell fire).
On a side note, since Muslims want to argue that there's something miraculous about Islam, perhaps they can make an argument based on Muhammad's teachings about personal hygiene. A Muslim could always argue that it's a miracle that Muhammad and his followers survived his teachings about personal hygiene, and that Allah must have been miraculously preserving Muhammad and the early Muslim community!
