The word(s) "sure" appears 262 time(s) in 243 verse(s) in Quran in Muhammad Pickthal translation.

(31) If only the People of the Scripture would believe and ward off (evil), surely We should remit their sins from them and surely We should bring them into Gardens of Delight.

(32) If they had observed the Torah and the Gospel and that which was revealed unto them from their Lord, they would surely have been nourished from above them and from beneath their feet. Among them there are people who are moderate, but many of them are of evil conduct.

(33) They surely disbelieve who say: Lo! Allah is the Messiah, son of Mary. The Messiah (himself) said: O Children of Israel, worship Allah, my Lord and your Lord. Lo! whoso ascribeth partners unto Allah, for him Allah hath forbidden paradise. His abode is the Fire. For evil-doers there will be no helpers.

(34) They surely disbelieve who say: Lo! Allah is the third of three; when there is no Allah save the One Allah. If they desist not from so saying a painful doom will fall on those of them who disbelieve.

(35) Thou seest many of them making friends with those who disbelieve. surely ill for them is that which they themselves send on before them: that Allah will be wroth with them and in the doom they will abide.

(36) O ye who believe! Allah will surely try you somewhat (in the matter) of the game which ye take with your hands and your spears, that Allah may know him who feareth Him in secret. Whoso transgresseth after this, for him there is a painful doom.

(37) A folk before you asked (for such disclosures) and then disbelieved therein.

(38) 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.

(39) Allah saith: This is a day in which their truthfulness profiteth the truthful, for theirs are Gardens underneath which rivers flow, wherein they are secure for ever, Allah taking pleasure in them and they in Him. That is the great triumph.

(40) Had we appointed him (Our messenger) an angel, We assuredly had made him (as) a man (that he might speak to men); and (thus) obscured for them (the truth) they (now) obscure.
