The word(s) "believers" appears 275 time(s) in 258 verse(s) in Quran in Muhammad Habib Shakir translation.

(181) And when you said to him to whom Allah had shown favor and to whom you had shown a favor: Keep your wife to yourself and be careful of (your duty to) Allah; and you concealed in your soul what Allah would bring to light, and you feared men, and Allah had a greater right that you should fear Him. But when Zaid had accomplished his want of her, We gave her to you as a wife, so that there should be no difficulty for the believers in respect of the wives of their adopted sons, when they have accomplished their want of them; and Allah's command shall be performed.

(182) He it is Who sends His blessings on you, and (so do) His angels, that He may bring you forth out of utter darkness into the light; and He is Merciful to the believers.

(183) And give to the believers the good news that they shall have a great grace from Allah.

(184) And be not compliant to the unbelievers and the hypocrites, and leave unregarded their annoying talk, and rely on Allah; and Allah is sufficient as a Protector.

(185) O Prophet! surely We have made lawful to you your wives whom you have given their dowries, and those whom your right hand possesses out of those whom Allah has given to you as prisoners of war, and the daughters of your paternal uncles and the daughters of your paternal aunts, and the daughters of your maternal uncles and the daughters of your maternal aunts who fled with you; and a believing woman if she gave herself to the Prophet, if the Prophet desired to marry her-- specially for you, not for the (rest of) believers; We know what We have ordained for them concerning their wives and those whom their right hands possess in order that no blame may attach to you; and Allah is Forgiving, Merciful.

(186) 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.

(187) Surely Allah has cursed the unbelievers and has prepared for them a burning fire,

(188) And certainly the Shaitan found true his conjecture concerning them, so they follow him, except a party of the believers.

(189) And those who disbelieve say: By no means will we believe in this Quran, nor in that which is before it; and could you see when the unjust shall be made to stand before their Lord, bandying words one with another! Those who were reckoned weak shall say to those who were proud: Had it not been for you we would certainly have been believers.

(190) And We never sent a warner to a town but those who led lives in ease in it said: We are surely disbelievers in what you are sent with.
