The word(s) "o you who believe" appears 88 time(s) in 88 verse(s) in Quran in Mohsin Khan translation.

(81) o you who believe! Why do you say that which you do not do?

(82) o you who believe! Shall I guide you to a trade that will save you from a painful torment?

(83) o you who believe! Be you helpers (in the Cause) of Allah as said 'Îsa (Jesus), son of Maryam (Mary), to the Hawariyyun (the disciples): "Who are my helpers (in the Cause) of Allah?" The Hawariyyun (the disciples) said: "We are Allah's helpers" (i.e. we will strive in His Cause!). Then a group of the Children of Israel believed and a group disbelieved. So We gave power to those who believed against their enemies, and they became the victorious (uppermost).

(84) o you who believe (Muslims)! When the call is proclaimed for the Salat (prayer) on Friday (Jumu'ah prayer), come to the remembrance of Allah [Jumu'ah religious talk (Khutbah) and Salat (prayer)] and leave off business (and every other thing). That is better for you if you did but know!

(85) o you who believe! Let not your properties or your children divert you from the remembrance of Allah. And whosoever does that, then they are the losers.

(86) o you who believe! Verily, among your wives and your children there are enemies for you (who may stop you from the obedience of Allah); therefore beware of them! But if you pardon (them) and overlook, and forgive (their faults), then verily Allah is Oft-Forgiving, Most Merciful.

(87) o you who believe! Ward off yourselves and your families against a Fire (Hell) whose fuel is men and stones, over which are (appointed) angels stern (and) severe, who disobey not, (from executing) the Commands they receive from Allah, but do that which they are commanded.

(88) o you who believe! Turn to Allah with sincere repentance! It may be that your Lord will expiate from you your sins, and admit you into Gardens under which rivers flow (Paradise) - the Day that Allah will not disgrace the Prophet (Muhammad صلى الله عليه وسلم) and those who believe with him. Their Light will run forward before them and (with their Records - Books of deeds) in their right hands. They will say: "Our Lord! Keep perfect our Light for us [and do not put it off till we cross over the Sirat (a slippery bridge over the Hell) safely] and grant us forgiveness. Verily, You are Able to do all things."
