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

(11) O ye who believe! Believe in Allah and His messenger and the Scripture which He hath revealed unto His messenger, and the Scripture which He revealed aforetime. Whoso disbelieveth in Allah and His angels and His scriptures and His messengers and the Last Day, he verily hath wandered far astray.

(12) Allah made a covenant of old with the Children of Israel and We raised among them twelve chieftains, and Allah said: Lo! I am with you. If ye establish worship and pay the poor-due, and believe in My messengers and support them, and lend unto Allah a kindly loan, surely I shall remit your sins, and surely I shall bring you into Gardens underneath which rivers flow. Whoso among you disbelieveth after this will go astray from a plain road.

(13) Lo! those who believe, and those who are Jews, and Sabaeans, and Christians - Whosoever believeth in Allah and the Last Day and doeth right - there shall no fear come upon them neither shall they grieve.

(14) Allah said: Lo! I send it down for you. And whoso disbelieveth of you afterward, him surely will I punish with a punishment wherewith I have not punished any of (My) creatures.

(15) We send not the messengers save as bearers of good news and warners. Whoso believeth and doeth right, there shall no fear come upon them neither shall they grieve.

(16) Lurk not on every road to threaten (wayfarers), and to turn away from Allah's path him who believeth in Him, and to seek to make it crooked. And remember, when ye were but few, how He did multiply you. And see the nature of the consequence for the corrupters!

(17) And if there is a party of you which believeth in that wherewith I have been sent, and there is a party which believeth not, then have patience until Allah judge between us. He is the Best of all who deal in judgment.

(18) Say (O Muhammad): O mankind! Lo! I am the messenger of Allah to you all - (the messenger of) Him unto Whom belongeth the Sovereignty of the heavens and the earth. There is no Allah save Him. He quickeneth and He giveth death. So believe in Allah and His messenger, the Prophet who can neither read nor write, who believeth in Allah and in His Words, and follow him that haply ye may be led aright.

(19) He only shall tend Allah's sanctuaries who believeth in Allah and the Last Day and observeth proper worship and payeth the poor-due and feareth none save Allah. For such (only) is it possible that they can be of the rightly guided.

(20) Count ye the slaking of a pilgrim's thirst and tendance of the Inviolable Place of Worship as (equal to the worth of) him who believeth in Allah and the Last Day, and striveth in the way of Allah? They are not equal in the sight of Allah. Allah guideth not wrongdoing folk.
