The word(s) "restrain" appears 10 time(s) in 10 verse(s) in Quran in Mohsin Khan translation.

(1) And whoever of you have not the means wherewith to wed free, believing women, they may wed believing girls from among those (slaves) whom your right hands possess, and Allah has full knowledge about your Faith; you are one from another. Wed them with the permission of their own folk (guardians, Auliya' or masters) and give them their Mahr according to what is reasonable; they (the above said captive and slave-girls) should be chaste, not committing illegal sex, nor taking boy-friends. And after they have been taken in wedlock, if they commit illegal sexual intercourse, their punishment is half that for free (unmarried) women. This is for him among you who is afraid of being harmed in his religion or in his body; but it is better for you that you practise self-restraint, and Allah is Oft-Forgiving, Most Merciful.

(2) Then fight (O Muhammad صلى الله عليه وسلم) in the Cause of Allah, you are not tasked (held responsible) except for yourself, and incite the believers (to fight along with you), it may be that Allah will restrain the evil might of the disbelievers. And Allah is Stronger in Might and Stronger in punishing.

(3) Except those who join a group, between you and whom there is a treaty (of peace), or those who approach you with their breasts restraining from fighting you as well as fighting their own people. Had Allah willed, indeed He would have given them power over you, and they would have fought you. So if they withdraw from you, and fight not against you, and offer you peace, then Allah has opened no way for you against them.

(4) You will find others that wish to have security from you and security from their people. Every time they are sent back to temptation, they yield thereto. If they withdraw not from you, nor offer you peace, nor restrain their hands, take (hold of) them and kill them wherever you find them. In their case, We have provided you with a clear warrant against them.

(5) (Remember) when Allah will say (on the Day of Resurrection). "O 'Îsa (Jesus), son of Maryam (Mary)! Remember My Favour to you and to your mother when I supported you with Ruh-ul-Qudus [Jibril (Gabriel)] so that you spoke to the people in the cradle and in maturity; and when I taught you writing, Al-Hikmah (the power of understanding), the Taurat (Torah) and the Injeel (Gospel); and when you made out of the clay a figure like that of a bird, by My Permission, and you breathed into it, and it became a bird by My Permission, and you healed those born blind, and the lepers by My Permission, and when you brought forth the dead by My Permission; and when I restrained the Children of Israel from you (when they resolved to kill you) as you came unto them with clear proofs, and the disbelievers among them said: 'This is nothing but evident magic.'"

(6) And beside them will be Qasirat-at-Tarf [chaste females (wives), restraining their glances (desiring none except their husbands)], with wide and beautiful eyes.

(7) And beside them will be Qasirat-at-Tarf [chaste females (wives) restraining their glances (desiring none except their husbands)], (and) of equal ages.

(8) Allah has promised you abundant spoils that you will capture, and He has hastened for you this, and He has restrained the hands of men from you: that it may be a sign for the believers, and that He may guide you to the Straight Path.

(9) Wherein both will be Qasirat-ut-Tarf [chaste females (wives) restraining their glances, desiring none except their husbands], with whom no man or jinni has had tamth before them.

(10) But as for him who feared standing before his Lord, and restrained himself from impure evil desires and lusts.
