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

(241) And Noah, said: "O my Lord! Leave not of the Unbelievers, a single one on earth!

(242) And We have set none but angels as Guardians of the Fire; and We have fixed their number only as a trial for Unbelievers,- in order that the People of the Book may arrive at certainty, and the believers may increase in Faith,- and that no doubts may be left for the People of the Book and the believers, and that those in whose hearts is a disease and the Unbelievers may say, "What symbol doth Allah intend by this?" Thus doth Allah leave to stray whom He pleaseth, and guide whom He pleaseth: and none can know the forces of thy Lord, except He and this is no other than a warning to mankind.

(243) But on this Day the believers will laugh at the Unbelievers:

(244) Will not the Unbelievers have been paid back for what they did?

(245) But on the contrary the Unbelievers reject (it).

(246) And they witnessed (all) that they were doing against the believers.

(247) Those who persecute (or draw into temptation) the believers, men and women, and do not turn in repentance, will have the Penalty of Hell: They will have the Penalty of the Burning Fire.

(248) And yet the Unbelievers (persist) in rejecting (the Truth)!

(249) Therefore grant a delay to the Unbelievers: Give respite to them gently (for awhile).
