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

(21) surely, those who reject Faith (disbelieve in Allah and in Muhammad صلى الله عليه وسلم) as being Allah's Messenger and in all that which he صلى الله عليه وسلم has brought from Allah), neither their properties, nor their offspring will avail them aught against Allah. They are the dwellers of the Fire, therein they will abide. (Tafsir At-Tabari).

(22) If a good befalls you, it grieves them, but if some evil overtakes you, they rejoice at it. But if you remain patient and become Al-Muttaqun [the pious - See V.2:2], not the least harm will their cunning do to you. surely, Allah surrounds all that they do.

(23) If a wound (and killing) has touched you, be sure a similar wound (and killing) has touched the others. And so are the days (good and not so good), We give to men by turns, that Allah may test those who believe, and that He may take martyrs from among you. And Allah likes not the Zalimun (polytheists and wrong-doers).

(24) And Allah did indeed fulfil His Promise to you when you were killing them (your enemy) with His Permission; until (the moment) you lost your courage and fell to disputing about the order, and disobeyed after He showed you (of the booty) which you love. Among you are some that desire this world and some that desire the Hereafter. Then He made you flee from them (your enemy), that He might test you. But surely, He forgave you, and Allah is Most Gracious to the believers.

(25) Those of you who turned back on the day the two hosts met (i.e. the battle of Uhud), it was Shaitan (Satan) who caused them to backslide (run away from the battlefield) because of some (sins) they had earned. But Allah, indeed, has forgiven them. surely, Allah is Oft-Forgiving, Most Forbearing.

(26) Is then one who follows (seeks) the good Pleasure of Allah (by not taking illegally a part of the booty) like the one who draws on himself the Wrath of Allah (by taking a part of the booty illegally - Ghulul)? - his abode is Hell, and worst, indeed is that destination!

(27) So they returned with Grace and Bounty from Allah. No harm touched them; and they followed the good Pleasure of Allah. And Allah is the Owner of Great Bounty.

(28) And there are, certainly, among the people of the Scripture (Jews and Christians), those who believe in Allah and in that which has been revealed to you, and in that which has been revealed to them, humbling themselves before Allah. They do not sell the Verses of Allah for a little price, for them is a reward with their Lord. surely, Allah is Swift in account.

(29) O mankind! Be dutiful to your Lord, Who created you from a single person (Adam), and from him (Adam) He created his wife [Hawwa (Eve)], and from them both He created many men and women; and fear Allah through Whom you demand (your mutual rights), and (do not cut the relations of) the wombs (kinship) . surely, Allah is Ever an All-Watcher over you.

(30) And give unto orphans their property and do not exchange (your) bad things for (their) good ones; and devour not their substance (by adding it) to your substance. surely, this is a great sin.
