The word(s) "instruct" appears 25 time(s) in 24 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) There is, in their stories, instruction for men endued with understanding. It is not a tale invented, but a confirmation of what went before it,- a detailed exposition of all things, and a guide and a mercy to any such as believe.

(12) And verily in cattle (too) will ye find an instructive sign. From what is within their bodies between excretions and blood, We produce, for your drink, milk, pure and agreeable to those who drink it.

(13) Allah commands justice, the doing of good, and liberality to kith and kin, and He forbids all shameful deeds, and injustice and rebellion: He instructs you, that ye may receive admonition.

(14) And in cattle (too) ye have an instructive example: from within their bodies We produce (milk) for you to drink; there are, in them, (besides), numerous (other) benefits for you; and of their (meat) ye eat;

(15) (Further, We sent a long line of prophets for your instruction). We sent Noah to his people: He said, "O my people! worship Allah! Ye have no other god but Him. Will ye not fear (Him)?"

(16) It is Allah Who alternates the Night and the Day: verily in these things is an instructive example for those who have vision!

(17) Behold, Luqman said to his son by way of instruction: "O my son! join not in worship (others) with Allah: for false worship is indeed the highest wrong-doing."

(18) We have not instructed the (Prophet) in Poetry, nor is it meet for him: this is no less than a Message and a Qur'an making things clear:

(19) Verily We have revealed the Book to thee in Truth, for (instructing) mankind. He, then, that receives guidance benefits his own soul: but he that strays injures his own soul. Nor art thou set over them to dispose of their affairs.

(20) Say: "What! Will ye instruct Allah about your religion? But Allah knows all that is in the heavens and on earth: He has full knowledge of all things.
