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

(71) Who is then more unjust than he who forges a lie against Allah or rejects His communications? (As for) those, their portion of the Book shall reach them, until when Our apostles come to them causing them to die, they shall say: Where is that which you used to call upon besides Allah? They would say: They are gone away from us; and they shall bear witness against themselves that they were unbelievers

(72) Who hinder (people) from Allah's way and seek to make it crooked, and they are disbelievers in the hereafter.

(73) And the inmates of the fire shall call out to the dwellers of the garden, saying: Pour on us some water or of that which Allah has given you. They shall say: Surely Allah has prohibited them both to the unbelievers.

(74) So We delivered him and those with him by mercy from Us, and We cut off the last of those who rejected Our communications and were not believers.

(75) The chief of those who behaved proudly among his people said to those who were considered weak, to those who believed from among them: Do you know that Salih is sent by his Lord? They said: Surely we are believers in what he has been sent with

(76) And to Madyan (We sent) their brother Shu'aib. He said: O my people! serve Allah, you have no god other than Him; clear proof indeed has come to you from your Lord, therefore give full measure and weight and do not diminish to men their things, and do not make mischief in the land after its reform; this is better for you if you are believers:

(77) These towns-- We relate to you some of their stories, and certainly their apostles came to them with clear arguments, but they would not believe in what they rejected at first; thus does Allah set a seal over the hearts of the unbelievers

(78) And when Musa came at Our appointed time and his Lord spoke to him, he said: My Lord! show me (Thyself), so that I may look upon Thee. He said: You cannot (bear to) see Me but look at the mountain, if it remains firm in its place, then will you see Me; but when his Lord manifested His glory to the mountain He made it crumble and Musa fell down in a swoon; then when he recovered, he said: Glory be to Thee, I turn to Thee, and I am the first of the believers.

(79) They ask you about the windfalls. Say: The windfalls are for Allah and the Apostle. So be careful of (your duty to) Allah and set aright matters of your difference, and obey Allah and His Apostle if you are believers.

(80) Those only are believers whose hearts become full of fear when Allah is mentioned, and when His communications are recited to them they increase them in faith, and in their Lord do they trust.
