The word(s) "arm" appears 115 time(s) in 99 verse(s) in Quran in Mohsin Khan translation.

(21) O you who believe! When you intend to offer As-Salat (the prayer), wash your faces and your hands (forearms) up to the elbows, rub (by passing wet hands over) your heads, and (wash) your feet up to ankles . If you are in a state of Janaba (i.e. after a sexual discharge), purify yourselves (bathe your whole body). But if you are ill or on a journey, or any of you comes after answering the call of nature, or you have been in contact with women (i.e. sexual intercourse), and you find no water, then perform Tayammum with clean earth and rub therewith your faces and hands. Allah does not want to place you in difficulty, but He wants to purify you, and to complete His Favour to you that you may be thankful.

(22) Say (O Muhammad صلى الله عليه وسلم to mankind): "How do you worship besides Allah something which has no power either to harm or benefit you? But it is Allah Who is the All-Hearer, All-Knower."

(23) And if Allah touches you with harm, none can remove it but He, and if He touches you with good, then He is Able to do all things.

(24) If their aversion (from you, O Muhammad صلى الله عليه وسلم and from that with which you have been sent) is hard on you, (and you cannot be patient of their harm to you), then if you were able to seek a tunnel in the earth or a ladder to the sky, so that you may bring them a sign (and you cannot do it, so be patient). And had Allah willed, He could have gathered them together (all) on true guidance, so be not you one of those who are Al-Jahilun (the ignorant).

(25) Say (O Muhammad صلى الله عليه وسلم): "Shall we invoke others besides Allah (false deities), that can do us neither good nor harm, and shall we turn back on our heels after Allah has guided us (to true Monotheism)? - like one whom the Shayatin (devils) have made to go astray in the land in confusion, his companions calling him to guidance (saying): 'Come to us.' " Say: "Verily, Allah's Guidance is the only guidance, and we have been commanded to submit (ourselves) to the Lord of the 'Alamin (mankind, jinn and all that exists);

(26) "And how should I fear those whom you associate in worship with Allah (though they can neither benefit nor harm), while you fear not that you have joined in worship with Allah things for which He has not sent down to you any authority. (So) which of the two parties has more right to be in security? If you but know."

(27) Verily, proofs have come to you from your Lord, so whosoever sees, will do so for (the good of) his ownself, and whosoever blinds himself, will do so to his own harm, and I (Muhammad صلى الله عليه وسلم) am not a watcher over you.

(28) 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.

(29) 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.

(30) 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."
