The word(s) "believe" appears 1522 time(s) in 1179 verse(s) in Quran in Mohsin Khan translation.

(511) See they not that We gradually reduce the land (of the disbelievers, by giving it to the believers, in war victories) from its outlying borders. And Allah judges, there is none to put back His Judgement and He is Swift at reckoning.

(512) And verily, those before them did devise plots, but all planning is Allah's. He knows what every person earns, and the disbelievers will know who gets the good end (final destination).

(513) And those who disbelieved, say: "You (O Muhammad صلى الله عليه و سلم) are not a Messenger." Say: "Sufficient as a witness between me and you is Allah and those too who have knowledge of the Scripture (such as 'Abdullah bin Salam and other Jews and Christians who embraced Islam)."

(514) Allah to Whom belongs all that is in the heavens and all that is in the earth! And woe unto the disbelievers from a severe torment.

(515) And (remember) when your Lord proclaimed: "If you give thanks (by accepting Faith and worshipping none but Allah), I will give you more (of My Blessings); but if you are thankless (i.e. disbelievers), verily My punishment is indeed severe."

(516) And Musa (Moses) said: "If you disbelieve, you and all on earth together, then verily Allah is Rich (Free of all needs), Owner of all Praise."

(517) Has not the news reached you, of those before you, the people of Nuh (Noah), and 'Ad, and Thamud? And those after them? None knows them but Allah. To them came their Messengers with clear proofs, but they put their hands in their mouths (biting them from anger) and said: "Verily, we disbelieve in that with which you have been sent, and we are really in grave doubt as to that to which you invite us (i.e. Islamic Monotheism)."

(518) Their Messengers said to them: "We are no more than human beings like you, but Allah bestows His Grace to whom He wills of His slaves. It is not ours to bring you an authority (proof) except by the Permission of Allah. And in Allah (Alone) let the believers put their trust.

(519) And those who disbelieved, said to their Messengers: "Surely, we shall drive you out of our land, or you shall return to our religion." So their Lord revealed to them: "Truly, We shall destroy the Zalimun (polytheists, disbelievers and wrong-doers).

(520) And they (the Messengers) sought victory and help [from their Lord (Allah)]; and every obstinate, arrogant dictator (who refuses to believe in the Oneness of Allah) was brought to a complete loss and destruction.
