The word(s) "believer" appears 350 time(s) in 314 verse(s) in Quran in Muhammad Pickthal translation.

(221) Is he who is a believer like unto him who is an evil-liver? They are not alike.

(222) O Prophet! Keep thy duty to Allah and obey not the disbelievers and the hypocrites. Lo! Allah is Knower, Wise.

(223) The Prophet is closer to the believers than their selves, and his wives are (as) their mothers. And the owners of kinship are closer one to another in the ordinance of Allah than (other) believers and the fugitives (who fled from Mecca), except that ye should do kindness to your friends. This is written in the Book (of nature).

(224) There were the believers sorely tried, and shaken with a mighty shock.

(225) Being sparing of their help to you (believers). But when the fear cometh, then thou (Muhammad) seest them regarding thee with rolling eyes like one who fainteth unto death. Then, when the fear departeth, they scald you with sharp tongues in their greed for wealth (from the spoil). Such have not believed. Therefor Allah maketh their deeds fruitless. And that is easy for Allah.

(226) And when the true believers saw the clans, they said: This is that which Allah and His messenger promised us. Allah and His messenger are true. It did but confirm them in their faith and resignation.

(227) Of the believers are men who are true to that which they covenanted with Allah. Some of them have paid their vow by death (in battle), and some of them still are waiting; and they have not altered in the least;

(228) And Allah repulsed the disbelievers in their wrath; they gained no good. Allah averted their attack from the believers. Allah is ever Strong, Mighty.

(229) And when thou saidst unto him on whom Allah hath conferred favour and thou hast conferred favour: Keep thy wife to thyself, and fear Allah. And thou didst hide in thy mind that which Allah was to bring to light, and thou didst fear mankind whereas Allah hath a better right that thou shouldst fear Him. So when Zeyd had performed that necessary formality (of divorce) from her, We gave her unto thee in marriage, so that (henceforth) there may be no sin for believers in respect of wives of their adopted sons, when the latter have performed the necessary formality (of release) from them. The commandment of Allah must be fulfilled.

(230) He it is Who blesseth you, and His angels (bless you), that He may bring you forth from darkness unto light; and He is ever Merciful to the believers.
