The word(s) "arm" appears 77 time(s) in 71 verse(s) in Quran in Muhammad Habib Shakir translation.

(51) He said: We will strengthen your arm with your brother, and We will give you both an authority, so that they shall not reach you; (go) with Our signs; you two and those who follow you shall be uppermost.

(52) And when harm afflicts men, they call upon their Lord, turning to Him, then when He makes them taste of mercy from Him, lo! some of them begin to associate (others) with their Lord,

(53) There is no harm in the Prophet doing that which Allah has ordained for him; such has been the course of Allah with respect to those who have gone before; and the command of Allah is a decree that is made absolute:

(54) O Prophet! say to your wives and your daughters and the women of the believers that they let down upon them their over-garments; this will be more proper, that they may be known, and thus they will not be given trouble; and Allah is Forgiving, Merciful.

(55) So on that day one of you shall not control profit or harm for another, and We will say to those who were unjust: Taste the chastisement of the fire which you called a lie.

(56) What! shall I take besides Him gods whose intercession, If the Beneficent Allah should desire to afflict me with a harm, shall not avail me aught, nor shall they be able to deliver me?

(57) This is an army plunging in without consideration along with you; no welcome for them, surely they shall enter fire.

(58) And should you ask them, Who created the heavens and the earth? They would most certainly say: Allah. Say: Have you then considered that what you call upon besides Allah, would they, if Allah desire to afflict me with harm, be the removers of His harm, or (would they), if Allah desire to show me mercy, be the withholders of His mercy? Say: Allah is sufficient for me; on Him do the reliant rely.

(59) So when harm afflicts a man he calls upon Us; then, when We give him a favor from Us, he says: I have been given it only by means of knowledge. Nay, it is a trial, but most of them do not know.

(60) And not alike are the good and the evil. Repel (evil) with what is best, when lo! he between whom and you was enmity would be as if he were a warm friend.
