The word(s) "believed" appears 108 time(s) in 100 verse(s) in Quran in Muhammad Pickthal translation.

(71) And when they became steadfast and believed firmly in Our revelations, We appointed from among them leaders who guided by Our command.

(72) 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.

(73) Those who were despised say unto those who were proud: Nay but (it was your) scheming night and day, when ye commanded us to disbelieve in Allah and set up rivals unto Him. And they are filled with remorse when they behold the doom; and We place carcans on the necks of those who disbelieved. Are they requited aught save what they used to do?

(74) When they disbelieved in it of yore. They aim at the unseen from afar off.

(75) Then seized I those who disbelieved, and how intense was My abhorrence!

(76) Lo! I have believed in your Lord, so hear me!

(77) Burn therein this day for that ye disbelieved.

(78) And they believed, therefor We gave them comfort for a while.

(79) (It is said unto them): This is (your plight) because, when Allah only was invoked, ye disbelieved, but when some partner was ascribed to Him ye were believing. But the command belongeth only to Allah, the Sublime, the Majestic.

(80) Have they not travelled in the land to see the nature of the consequence for those who disbelieved before them? They were mightier than these in power and (in the) traces (which they left behind them) in the earth. Yet Allah seized them for their sins, and they had no protector from Allah.
