The word(s) "believeth" appears 53 time(s) in 50 verse(s) in Quran in Muhammad Pickthal translation.

(31) Save him who repenteth and believeth and doth righteous work; as for such, Allah will change their evil deeds to good deeds. Allah is ever Forgiving, Merciful.

(32) But those who had been given knowledge said: Woe unto you! The reward of Allah for him who believeth and doeth right is better, and only the steadfast will obtain it.

(33) Whoso disbelieveth must (then) bear the consequences of his disbelief, while those who do right make provision for themselves -

(34) And whosoever disbelieveth, let not his disbelief afflict thee (O Muhammad). Unto Us is their return, and We shall tell them what they did. Lo! Allah is Aware of what is in the breasts (of men).

(35) And he had no warrant whatsoever against them, save that We would know him who believeth in the Hereafter from him who is in doubt thereof; and thy Lord (O Muhammad) taketh note of all things.

(36) And it is not your wealth nor your children that will bring you near unto Us, but he who believeth and doeth good (he draweth near). As for such, theirs will be twofold reward for what they did and they will dwell secure in lofty halls.

(37) He it is Who hath made you regents in the earth; so he who disbelieveth, his disbelief be on his own head. Their disbelief increaseth for the disbelievers, in their Lord's sight, naught save abhorrence. Their disbelief increaseth for the disbelievers naught save loss.

(38) Is he whose bosom Allah hath expanded for Al-Islam, so that he followeth a light from his Lord, (as he who disbelieveth)? Then woe unto those whose hearts are hardened against remembrance of Allah. Such are in plain error.

(39) And whoso bringeth the truth and believeth therein - Such are the dutiful.

(40) Moses said: Lo! I seek refuge in my Lord and your Lord from every scorner who believeth not in a Day of Reckoning.
