The word(s) "believe" appears 1141 time(s) in 920 verse(s) in Quran in Muhammad Pickthal translation.

(321) And know that whatever ye take as spoils of war, lo! a fifth thereof is for Allah, and for the messenger and for the kinsman (who hath need) and orphans and the needy and the wayfarer, if ye believe in Allah and that which We revealed unto Our slave on the Day of Discrimination, the day when the two armies met. And Allah is Able to do all things.

(322) O ye who believe! When ye meet an army, hold firm and think of Allah much, that ye may be successful.

(323) If thou couldst see how the angels receive those who disbelieve, smiting faces and their backs and (saying): Taste the punishment of burning!

(324) (Their way is) as the way of Pharaoh's folk and those before them; they disbelieved the revelations of Allah, and Allah took them in their sins. Lo! Allah is Strong, severe in punishment.

(325) Lo! the worst of beasts in Allah's sight are the ungrateful who will not believe.

(326) And let not those who disbelieve suppose that they can outstrip (Allah's Purpose). Lo! they cannot escape.

(327) And if they would deceive thee, then lo! Allah is Sufficient for thee. He it is Who supporteth thee with His help and with the believers,

(328) And (as for the believers) hath attuned their hearts. If thou hadst spent all that is in the earth thou couldst not have attuned their hearts, but Allah hath attuned them. Lo! He is Mighty, Wise.

(329) O Prophet! Allah is Sufficient for thee and those who follow thee of the believers.

(330) O Prophet! Exhort the believers to fight. If there be of you twenty steadfast they shall overcome two hundred, and if there be of you a hundred (steadfast) they shall overcome a thousand of those who disbelieve, because they (the disbelievers) are a folk without intelligence.
