The word(s) "donkey" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Or (take) the similitude of one who passed by a hamlet, all in ruins to its roofs. He said: "Oh! how shall Allah bring it (ever) to life, after (this) its death?" but Allah caused him to die for a hundred years, then raised him up (again). He said: "How long didst thou tarry (thus)?" He said: (Perhaps) a day or part of a day." He said: "Nay, thou hast tarried thus a hundred years; but look at thy food and thy drink; they show no signs of age; and look at thy donkey: And that We may make of thee a sign unto the people, Look further at the bones, how We bring them together and clothe them with flesh." When this was shown clearly to him, he said: "I know that Allah hath power over all things."

(2) And (He has created) horses, mules, and donkeys, for you to ride and use for show; and He has created (other) things of which ye have no knowledge.

(3) The similitude of those who were charged with the (obligations of the) Mosaic Law, but who subsequently failed in those (obligations), is that of a donkey which carries huge tomes (but understands them not). Evil is the similitude of people who falsify the Signs of Allah: and Allah guides not people who do wrong.
