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

(241) And indeed We have set forth for mankind, in this Qur'an every kind of parable. But if you (O Muhammad صلى الله عليه وسلم) bring to them any sign or proof (as an evidence for the truth of your Prophethood), the disbelievers are sure to say (to the believers): "You follow nothing but falsehood, and magic."

(242) See you not (O men) that Allah has subjected for you whatsoever is in the heavens and whatsoever is in the earth, and has completed and perfected His Graces upon you, (both) apparent (i.e. Islamic Monotheism, and the lawful pleasures of this world, including health, good looks, etc.) and hidden [i.e. One's Faith in Allah (of Islamic Monotheism) knowledge, wisdom, guidance for doing righteous deeds, and also the pleasures and delights of the Hereafter in Paradise]? Yet of mankind is he who disputes about Allah without knowledge or guidance or a Book giving light!

(243) And if We had willed, surely We would have given every person his guidance, but the Word from Me took effect (about evil-doers), that I will fill Hell with jinn and mankind together.

(244) Then taste you (the torment of the Fire) because of your forgetting the Meeting of this Day of yours. surely We too will forget you: so taste you the abiding torment for what you used to do.

(245) And if the enemy had entered from all sides (of the city), and they had been exhorted to Al-Fitnah (i.e. to renegade from Islam to polytheism), they would surely have committed it and would have hesitated thereupon but little.

(246) surely, Shaitan (Satan) is an enemy to you, so take (treat) him as an enemy. He only invites his Hizb (followers) that they may become the dwellers of the blazing Fire.

(247) And Allah did create you (Adam) from dust, then from Nutfah (male and female discharge semen drops i.e. Adam's offspring), then He made you pairs (male and female). And no female conceives or gives birth but with His Knowledge. And no aged man is granted a length of life nor is a part cut off from his life (or another man's life), but is in a Book (Al-Lauh Al-Mahfuz ) surely, that is easy for Allah.

(248) Verily, those who recite the Book of Allah (this Qur'an), and perform As-Salat (Iqamat-as-Salat), and spend (in charity) out of what We have provided for them, secretly and openly, they hope for a (sure) trade-gain that will never perish.

(249) They (people) said: "For us, we see an evil omen from you: if you cease not, we will surely stone you, and a painful torment will touch you from us."

(250) And surely, all - everyone of them will be brought before Us.
