The word(s) "believers" appears 293 time(s) in 249 verse(s) in Quran in Abdullah Yusuf Ali translation.

(161) Behold! Thou didst say to one who had received the grace of Allah and thy favour: "Retain thou (in wedlock) thy wife, and fear Allah." But thou didst hide in thy heart that which Allah was about to make manifest: thou didst fear the people, but it is more fitting that thou shouldst fear Allah. Then when Zaid had dissolved (his marriage) with her, with the necessary (formality), We joined her in marriage to thee: in order that (in future) there may be no difficulty to the believers in (the matter of) marriage with the wives of their adopted sons, when the latter have dissolved with the necessary (formality) (their marriage) with them. And Allah's command must be fulfilled.

(162) He it is Who sends blessings on you, as do His angels, that He may bring you out from the depths of Darkness into Light: and He is Full of Mercy to the believers.

(163) Then give the Glad Tidings to the believers, that they shall have from Allah a very great Bounty.

(164) And obey not (the behests) of the Unbelievers and the Hypocrites, and heed not their annoyances, but put thy Trust in Allah. For enough is Allah as a Disposer of affairs.

(165) O Prophet! We have made lawful to thee thy wives to whom thou hast paid their dowers; and those whom thy right hand possesses out of the prisoners of war whom Allah has assigned to thee; and daughters of thy paternal uncles and aunts, and daughters of thy maternal uncles and aunts, who migrated (from Makka) with thee; and any believing woman who dedicates her soul to the Prophet if the Prophet wishes to wed her;- this only for thee, and not for the believers (at large); We know what We have appointed for them as to their wives and the captives whom their right hands possess;- in order that there should be no difficulty for thee. And Allah is Oft-Forgiving, Most Merciful.

(166) Verily Allah has cursed the Unbelievers and prepared for them a Blazing Fire,-

(167) (With the result) that Allah has to punish the Hypocrites, men and women, and the Unbelievers, men and women, and Allah turns in Mercy to the believers, men and women: for Allah is Oft-Forgiving, Most Merciful.

(168) The Unbelievers say, "Never to us will come the Hour": Say, "Nay! but most surely, by my Lord, it will come upon you;- by Him Who knows the unseen,- from Whom is not hidden the least little atom in the heavens or on earth: Nor is there anything less than that, or greater, but is in the Record Perspicuous:

(169) The Unbelievers say (in ridicule): "Shall we point out to you a man that will tell you, when ye are all scattered to pieces in disintegration, that ye shall (then be raised) in a New Creation?

(170) The Unbelievers say: "We shall neither believe in this scripture nor in (any) that (came) before it." Couldst thou but see when the wrong-doers will be made to stand before their Lord, throwing back the word (of blame) on one another! Those who had been despised will say to the arrogant ones: "Had it not been for you, we should certainly have been believers!"
