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

(61) Their Lord giveth them good tidings of mercy from Him, and acceptance, and Gardens where enduring pleasure will be theirs;

(62) O ye who believe! Choose not your fathers nor your brethren for friends if they take pleasure in disbelief rather than faith. Whoso of you taketh them for friends, such are wrong-doers.

(63) O ye who believe! What aileth you that when it is said unto you: Go forth in the way of Allah, ye are bowed down to the ground with heaviness. Take ye pleasure in the life of the world rather than in the Hereafter? The comfort of the life of the world is but little in the Hereafter.

(64) Had it been a near adventure and an easy journey they had followed thee, but the distance seemed too far for them. Yet will they swear by Allah (saying): If we had been able we would surely have set out with you. They destroy their souls, and Allah knoweth that they verily are liars.

(65) And if they had wished to go forth they would assuredly have made ready some equipment, but Allah was averse to their being sent forth and held them back and it was said (unto them): Sit ye with the sedentary!

(66) Of them is he who saith: Grant me leave (to stay at home) and tempt me not. surely it is into temptation that they (thus) have fallen. Lo! hell verily is all around the disbelievers.

(67) Had they but found a refuge, or caverns, or a place to enter, they surely had resorted thither swift as runaways.

(68) Hath not the fame of those before them reached them - the folk of Noah, A'ad, Thamud, the folk of Abraham, the dwellers of Midian and the disasters (which befell them)? Their messengers (from Allah) came unto them with proofs (of Allah's Sovereignty). So Allah surely wronged them not, but they did wrong themselves.

(69) And as for those who chose a place of worship out of opposition and disbelief, and in order to cause dissent among the believers, and as an outpost for those who warred against Allah and His messenger aforetime, they will surely swear: We purposed naught save good. Allah beareth witness that they verily are liars.

(70) Is he who founded his building upon duty to Allah and His good pleasure better; or he who founded his building on the brink of a crumbling, overhanging precipice so that it toppled with him into the fire of hell? Allah guideth not wrongdoing folk.
