The word(s) "harm" appears 78 time(s) in 68 verse(s) in Quran in Mohsin Khan translation.

(21) And to Thamud (people, We sent) their brother Salih. He said: "O my people! Worship Allah! You have no other Ilah (God) but Him. (La ilaha illallah: none has the right to be worshipped but Allah). Indeed there has come to you a clear sign (the miracle of the coming out of a huge she-camel from the midst of a rock) from your Lord. This she-camel of Allah is a sign unto you; so you leave her to graze in Allah's earth, and touch her not with harm, lest a painful torment should seize you.

(22) And We divided them into twelve tribes (as distinct) nations. We revealed to Musa (Moses) when his people asked him for water (saying): "Strike the stone with your stick", and there gushed forth out of it twelve springs, each group knew its own place for water. We shaded them with the clouds and sent down upon them Al-Manna and the quails (saying): "Eat of the good things with which We have provided you." They harmed Us not but they used to harm themselves.

(23) Say (O Muhammad صلى الله عليه وسلم): "I possess no power over benefit or harm to myself except as Allah wills. If I had the knowledge of the Ghaib (Unseen), I should have secured for myself an abundance of wealth, and no evil should have touched me. I am but a warner, and a bringer of glad tidings unto people who believe."

(24) If you march not forth, He will punish you with a painful torment and will replace you by another people; and you cannot harm Him at all, and Allah is Able to do all things.

(25) And as for those who put up a mosque by way of harm and disbelief and to disunite the believers and as an outpost for those who warred against Allah and His Messenger (Muhammad صلى الله عليه وسلم) aforetime, they will indeed swear that their intention is nothing but good. Allah bears witness that they are certainly liars.

(26) And when harm touches man, he invokes Us, lying on his side, or sitting or standing. But when We have removed his harm from him, he passes on as if he had never invoked Us for a harm that touched him! Thus it is made fair-seeming to the Musrifun that which they used to do.

(27) And they worship besides Allah things that harm them not, nor profit them, and they say: "These are our intercessors with Allah." Say: "Do you inform Allah of that which He knows not in the heavens and on the earth?" Glorified and Exalted is He above all that which they associate as partners (with Him)!

(28) Say (O Muhammad صلى الله عليه وسلم): "I have no power over any harm or profit to myself except what Allah may will. For every Ummah (a community or a nation), there is a term appointed; when their term comes, neither can they delay it nor can they advance it an hour (or a moment)." (Tafsir Al-Qurtubi).

(29) "And invoke not besides Allah, any such that will neither profit you nor harm you, but if (in case) you did so, you shall certainly be one of the Zalimun (polytheists and wrong-doers). "

(30) And if Allah touches you with harm, there is none who can remove it but He, and if He intends any good for you, there is none who can repel His Favour which He causes it to reach whomsoever of His slaves He wills. And He is the Oft-Forgiving, the Most Merciful.
