The word(s) "sure" appears 262 time(s) in 243 verse(s) in Quran in Muhammad Pickthal translation.

(41) Say (O Muhammad, to the disbelievers): I say not unto you (that) I possess the treasures of Allah, nor that I have knowledge of the Unseen; and I say not unto you: Lo! I am an angel. I follow only that which is inspired in me. Say: Are the blind man and the seer equal? Will ye not then take thought?

(42) Then are they restored unto Allah, their Lord, the Just. surely His is the judgment. And He is the most swift of reckoners.

(43) And when he saw the moon uprising, he exclaimed: This is my Lord. But when it set, he said: Unless my Lord guide me, I surely shall become one of the folk who are astray.

(44) And they measure not the power of Allah its true measure when they say: Allah hath naught revealed unto a human being. Say (unto the Jews who speak thus): Who revealed the Book which Moses brought, a light and guidance for mankind, which ye have put on parchments which ye show, but ye hide much (thereof), and (by which) ye were taught that which ye knew not yourselves nor (did) your fathers (know it)? Say: Allah. Then leave them to their play of cavilling.

(45) That the hearts of those who believe not in the Hereafter may incline thereto, and that they may take pleasure therein, and that they may earn what they are earning.

(46) Lo! that which ye are promised will surely come to pass, and ye cannot escape.

(47) And approach not the wealth of the orphan save with that which is better, till he reach maturity. Give full measure and full weight, in justice. We task not any soul beyond its scope. And if ye give your word, do justice thereunto, even though it be (against) a kinsman; and fulfil the covenant of Allah. This He commandeth you that haply ye may remember.

(48) Or lest ye should say: If the Scripture had been revealed unto us, we surely had been better guided than are they. Now hath there come unto you a clear proof from your Lord, a guidance and mercy; and who doeth greater wrong than he who denieth the revelations of Allah, and turneth away from them? We award unto those who turn away from Our revelations an evil doom because of their aversion.

(49) He said: Go forth from hence, degraded, banished. As for such of them as follow thee, surely I will fill hell with all of you.

(50) They said: Our Lord! We have wronged ourselves. If thou forgive us not and have not mercy on us, surely we are of the lost!
