The word(s) "believer" appears 651 time(s) in 556 verse(s) in Quran in Mohsin Khan translation.

(131) This (is the fact) and surely, Allah weakens the deceitful plots of the disbelievers.

(132) (O disbelievers) if you ask for a judgement, now has the judgement come unto you; and if you cease (to do wrong), it will be better for you, and if you return (to the attack), so shall We return, and your forces will be of no avail to you, however numerous they be; and verily, Allah is with the believers.

(133) Verily! The worst of (moving) living creatures with Allah are the deaf and the dumb, who understand not (i.e. the disbelievers).

(134) And (remember) when the disbelievers plotted against you (O Muhammad صلى الله عليه وسلم) to imprison you, or to kill you, or to get you out (from your home, i.e. Makkah); they were plotting and Allah too was plotting; and Allah is the Best of those who plot.

(135) In order that Allah may distinguish the wicked (disbelievers, polytheists and doers of evil deeds) from the good (believers of Islamic Monotheism and doers of righteous deeds), and put the wicked (disbelievers, polytheists and doers of evil deeds) one over another, heap them together and cast them into Hell. Those! it is they who are the losers.

(136) (And remember) when you (the Muslim army) were on the near side of the valley, and they on the farther side, and the caravan on the ground lower than you. Even if you had made a mutual appointment to meet, you would certainly have failed in the appointment, but (you met) that Allah might accomplish a matter already ordained (in His Knowledge), so that those who were to be destroyed (for their rejecting the Faith) might be destroyed after a clear evidence, and those who were to live (i.e. believers) might live after a clear evidence. And surely, Allah is All-Hearer, All-Knower.

(137) And (remember) when you met (the army of the disbelievers on the Day of the battle of Badr), He showed them to you as few in your eyes and He made you appear as few in their eyes, so that Allah might accomplish a matter already ordained (in His Knowledge), and to Allah return all matters (for decision).

(138) And if they intend to deceive you, then verily, Allah is All-Sufficient for you. He it is Who has supported you with His Help and with the believers.

(139) And He has united their (i.e. believers') hearts. If you had spent all that is in the earth, you could not have united their hearts, but Allah has united them. Certainly He is All-Mighty, All-Wise.

(140) O Prophet (Muhammad صلى الله عليه وسلم)! Allah is Sufficient for you and for the believers who follow you.
