The word(s) "sure" appears 1640 time(s) in 1473 verse(s) in Quran in Muhammad Habib Shakir translation.

(241) And they say: Why has not a sign been sent down to him from his Lord? Say: surely Allah is able to send down a sign, but most of them do not know.

(242) Say: I do not say to you, I have with me the treasures of Allah, nor do I know the unseen, nor do I say to you that I am an angel; I do not follow aught save that which is revealed to me. Say: Are the blind and the seeing one alike? Do you not then reflect?

(243) Say: surely I have manifest proof from my Lord and you call it a lie; I have not with me that which you would hasten; the judgment is only Allah's; He relates the truth and He is the best of deciders.

(244) Then are they sent back to Allah, their Master, the True one; now surely His is the judgment and He is swiftest in taking account.

(245) Say: Shall we call on that besides Allah, which does not benefit us nor harm us, and shall we be returned back on our heels after Allah has guided us, like him whom the Shaitans have made to fall down perplexed in the earth? He has companions who call him to the right way, (saying): Come to us. Say: surely the guidance of Allah, that is the (true) guidance, and we are commanded that we should submit to the Lord of the worlds.

(246) And when Ibrahim said to his sire, Azar: Do you take idols for gods? surely I see you and your people in manifest error.

(247) And thus did We show Ibrahim the kingdom of the heavens and the earth and that he might be of those who are sure.

(248) Then when he saw the sun rising, he said: Is this my Lord? Is this the greatest? So when it set, he said: O my people! surely I am clear of what you set up (with Allah).

(249) surely I have turned myself, being upright, wholly to Him Who originated the heavens and the earth, and I am not of the polytheists.

(250) And how should I fear what you have set up (with Him), while you do not fear that you have set up with Allah that for which He has not sent down to you any authority; which then of the two parties is surer of security, if you know?
