The word(s) "sure" appears 226 time(s) in 213 verse(s) in Quran in Abdullah Yusuf Ali translation.

(171) And in the creation of yourselves and the fact that animals are scattered (through the earth), are Signs for those of assured Faith.

(172) If any one does a righteous deed, it ensures to the benefit of his own soul; if he does evil, it works against (his own soul). In the end will ye (all) be brought back to your Lord.

(173) These are clear evidences to men and a Guidance and Mercy to those of assured Faith.

(174) And on the Day that the Unbelievers will be placed before the Fire, (It will be said to them): "Ye received your good things in the life of the world, and ye took your pleasure out of them: but today shall ye be recompensed with a Penalty of humiliation: for that ye were arrogant on earth without just cause, and that ye (ever) transgressed."

(175) This because they followed that which called forth the Wrath of Allah, and they hated Allah's good pleasure; so He made their deeds of no effect.

(176) Had We so wiled, We could have shown them up to thee, and thou shouldst have known them by their marks: but surely thou wilt know them by the tone of their speech! And Allah knows all that ye do.

(177) Allah's Good Pleasure was on the Believers when they swore Fealty to thee under the Tree: He knew what was in their hearts, and He sent down Tranquillity to them; and He rewarded them with a speedy Victory;

(178) Muhammad is the messenger of Allah; and those who are with him are strong against Unbelievers, (but) compassionate amongst each other. Thou wilt see them bow and prostrate themselves (in prayer), seeking Grace from Allah and (His) Good Pleasure. On their faces are their marks, (being) the traces of their prostration. This is their similitude in the Taurat; and their similitude in the Gospel is: like a seed which sends forth its blade, then makes it strong; it then becomes thick, and it stands on its own stem, (filling) the sowers with wonder and delight. As a result, it fills the Unbelievers with rage at them. Allah has promised those among them who believe and do righteous deeds forgiveness, and a great Reward.

(179) On the earth are signs for those of assured Faith,

(180) Or are the Treasures of thy Lord with them, or are they the managers (of affairs)?
