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

(81) Say (O Muhammad صلى الله عليه و سلم) to the believers to forgive those who (harm them and) hope not for the Days of Allah (i.e. His Recompense), that He may recompense people, according to what they have earned (i.e. to punish these disbelievers who harm the believers).

(82) Verily, those who disbelieve, and hinder (men) from the Path of Allah (i.e. Islam), and oppose the Messenger (صلى الله عليه وسلم) (by standing against him and hurting him), after the guidance has been clearly shown to them, they will not harm Allah in the least, but He will make their deeds fruitless,

(83) Verily, those who give Bai'ah (pledge) to you (O Muhammad صلى الله عليه وسلم) they are giving Bai'ah (pledge) to Allah. The Hand of Allah is over their hands. Then whosoever breaks his pledge, breaks it only to his own harm; and whosoever fulfils what he has covenanted with Allah, He will bestow on him a great reward.

(84) O you who believe! If a Fasiq (liar - evil person) comes to you with any news, verify it, lest you should harm people in ignorance, and afterwards you become regretful for what you have done.

(85) Secret counsels (conspiracies) are only from Shaitan (Satan), in order that he may cause grief to the believers. But he cannot harm them in the least, except as Allah permits. And in Allah let the believers put their trust .

(86) Lodge them (the divorced women) where you dwell, according to your means, and do not harm them so as to straiten them (that they be obliged to leave your house). And if they are pregnant, then spend on them till they lay down their burden. Then if they give suck to the children for you, give them their due payment, and let each of you accept the advice of the other in a just way. But if you make difficulties for one another, then some other woman may give suck for him (the father of the child).

(87) And Maryam (Mary), the daughter of 'Imran who guarded her chastity. And We breathed into (the sleeve of her shirt or her garment) through Our Ruh [i.e. Jibril (Gabriel) ], and she testified to the truth of the Words of her Lord [i.e. believed in the Words of Allah: "Be!" - and he was; that is 'Îsa (Jesus), son of Maryam (Mary) as a Messenger of Allah], and (also believed in) His Scriptures, and she was of the Qanitun (i.e. obedient to Allah) .

(88) Who is he besides the Most Gracious that can be an army to you to help you? The disbelievers are in nothing but delusion.

(89) And verily, every time I called unto them that You might forgive them, they thrust their fingers into their ears, covered themselves up with their garments, and persisted (in their refusal), and magnified themselves in pride.

(90) Say: "It is not in my power to cause you harm, or to bring you to the Right Path."
