The word(s) "donkey" appears 4 time(s) in 4 verse(s) in Quran in Mohsin Khan translation.

(1) Or like the one who passed by a town while it had tumbled over its roofs. He said: "Oh! How will Allah ever bring it to life after its death?" So Allah caused him to die for a hundred years, then raised him up (again). He said: "How long did you remain (dead)?" He (the man) said: "(Perhaps) I remained (dead) a day or part of a day". He said: "Nay, you have remained (dead) for a hundred years, look at your food and your drink, they show no change; and look at your donkey! And thus We have made of you a sign for the people. Look at the bones, how We bring them together and clothe them with flesh". When this was clearly shown to him, he said, "I know (now) that Allah is Able to do all things."

(2) And (He has created) horses, mules and donkeys, for you to ride and as an adornment. And He creates (other) things of which you have no knowledge.

(3) The likeness of those who were entrusted with the (obligation of the) Taurat (Torah) (i.e. to obey its commandments and to practise its laws), but who subsequently failed in those (obligations), is as the likeness of a donkey which carries huge burdens of books (but understands nothing from them). How bad is the example of people who deny the Ayat (proofs, evidence, verses, signs, revelations) of Allah. And Allah guides not the people who are Zalimun (polytheists, wrong-doers, disbelievers).

(4) As if they were (frightened) wild donkeys.
