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

(61) He who is averted from (such a torment) on that Day, (Allah) has surely been Merciful to him. And that would be the obvious success.

(62) Verily, (many) Messengers were denied before you (O Muhammad صلى الله عليه وسلم), but with patience they bore the denial, and they were hurt; till Our Help reached them, and none can alter the Words (Decisions) of Allah. surely there has reached you the information (news) about the Messengers (before you).

(63) Say (O Muhammad صلى الله عليه وسلم): "I don't tell you that with me are the treasures of Allah, nor (that) I know the Unseen; nor I tell you that I am an angel. I but follow what is revealed to me." Say: "Are the blind and the one who sees equal? Will you not then take thought?"

(64) When those who believe in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) come to you, say: "Salamun 'Alaikum" (peace be on you); your Lord has written (prescribed) Mercy for Himself, so that if any of you does evil in ignorance, and thereafter repents and does righteous good deeds (by obeying Allah), then surely, He is Oft-Forgiving, Most Merciful.

(65) Then they are returned to Allah, their True Maula [True Master (God), the Just Lord (to reward them)]. surely, for Him is the judgement and He is the Swiftest in taking account.

(66) When he saw the moon rising up, he said: "This is my lord." But when it set, he said: "Unless my Lord guides me, I shall surely be among the people who went astray."

(67) And they swear their strongest oaths by Allah, that if there came to them a sign, they would surely believe therein. Say: "Signs are but with Allah and what will make you (Muslims) perceive that (even) if it (the sign) came, they will not believe?"

(68) And why should you not eat of that (meat) on which Allah's Name has been pronounced (at the time of slaughtering the animal), while He has explained to you in detail what is forbidden to you, except under compulsion of necessity? And surely many do lead (mankind) astray by their own desires through lack of knowledge. Certainly your Lord knows best the transgressors.

(69) Eat not (O believers) of that (meat) on which Allah's Name has not been pronounced (at the time of the slaughtering of the animal), for sure it is Fisq (a sin and disobedience of Allah). And certainly, the Shayatin (devils) do inspire their friends (from mankind) to dispute with you, and if you obey them [by making Al-Maitah (a dead animal) legal by eating it], then you would indeed be Mushrikun (polytheists); [because they (devils and their friends) made lawful to you to eat that which Allah has made unlawful to eat and you obeyed them by considering it lawful to eat, and by doing so you worshipped them; and to worship others besides Allah is polytheism].

(70) surely, that which you are promised will verily come to pass, and you cannot escape (from the punishment of Allah).
