The word(s) "sure" appears 334 time(s) in 314 verse(s) in Quran in Mohsin Khan translation.

(271) And if you ask them who created them, they will surely say: "Allah." How then are they turned away (from the worship of Allah, Who created them)?

(272) (Allah said): "Depart you with My slaves by night. surely, you will be pursued.

(273) On the Day when those who disbelieve (in the Oneness of Allah - Islamic Monotheism) will be exposed to the Fire (it will be said): "You received your good things in the life of the world, and you took your pleasure therein. Now this Day you shall be recompensed with a torment of humiliation, because you were arrogant in the land without a right, and because you used to rebel against Allah's Command (disobey Allah).

(274) And remember (Hud) the brother of 'Ad, when he warned his people in Al-Ahqaf (the curved sand-hills in the southern part of Arabian Peninsula). And surely, there have passed away warners before him and after him (saying): "Worship none but Allah; truly, I fear for you the torment of a mighty Day (i.e. the Day of Resurrection)."

(275) Do they not see that Allah, Who created the heavens and the earth, and was not wearied by their creation, is Able to give life to the dead? Yes, He surely is Able to do all things.

(276) Had We willed, We could have shown them to you, and you should have known them by their marks; but surely, you will know them by the tone of their speech! And Allah knows (all) your deeds.

(277) And surely, We shall try you till We test those who strive hard (for the Cause of Allah) and As-Sabirun (the patient), and We shall test your facts (i.e. the one who is a liar, and the one who is truthful).

(278) Muhammad (صلى الله عليه وسلم) is the Messenger of Allah. And those who are with him are severe against disbelievers, and merciful among themselves. You see them bowing and falling down prostrate (in prayer), seeking Bounty from Allah and (His) Good Pleasure. The mark of them (i.e. of their Faith) is on their faces (foreheads) from the traces of prostration (during prayers). This is their description in the Taurat (Torah). But their description in the Injeel (Gospel) is like a (sown) seed which sends forth its shoot, then makes it strong, and becomes thick and it stands straight on its stem, delighting the sowers, that He may enrage the disbelievers with them. Allah has promised those among them who believe (i.e. all those who follow Islamic Monotheism, the religion of Prophet Muhammad صلى الله عليه وسلم till the Day of Resurrection) and do righteous good deeds, forgiveness and a mighty reward (i.e. Paradise).

(279) And know that among you there is the Messenger of Allah (صلى الله عليه وسلم). If he were to obey you (i.e. follow your opinions and desires) in much of the matter, you would surely be in trouble. But Allah has endeared the Faith to you and has beautified it in your hearts, and has made disbelief, wickedness and disobedience (to Allah and His Messenger صلى الله عليه وسلم) hateful to you. Such are they who are the rightly guided.

(280) Verily, that which you are promised (i.e. Resurrection in the Hereafter and receiving the reward or punishment of good or bad deeds) is surely true.
