The word(s) "surely" appears 50 time(s) in 49 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) When they had had their throw, Moses said: "What ye have brought is sorcery: Allah will surely make it of no effect: for Allah prospereth not the work of those who make mischief.

(12) And Noah called upon his Lord, and said: "O my Lord! surely my son is of my family! and Thy promise is true, and Thou art the justest of Judges!"

(13) He said: "Before any food comes (in due course) to feed either of you, I will surely reveal to you the truth and meaning of this ere it befall you: that is part of the (duty) which my Lord hath taught me. I have (I assure you) abandoned the ways of a people that believe not in Allah and that (even) deny the Hereafter.

(14) "Nor do I absolve my own self (of blame): the (human) soul is certainly prone to evil, unless my Lord do bestow His Mercy: but surely my Lord is Oft-forgiving, Most Merciful."

(15) We created not the heavens, the earth, and all between them, but for just ends. And the Hour is surely coming (when this will be manifest). So overlook (any human faults) with gracious forgiveness.

(16) He said: "Seest Thou? this is the one whom Thou hast honoured above me! If Thou wilt but respite me to the Day of Judgment, I will surely bring his descendants under my sway - all but a few!"

(17) Thus did We make their case known to the people, that they might know that the promise of Allah is true, and that there can be no doubt about the Hour of Judgment. Behold, they dispute among themselves as to their affair. (Some) said, "Construct a building over them": Their Lord knows best about them: those who prevailed over their affair said, "Let us surely build a place of worship over them."

(18) "Nor do I deem that the Hour (of Judgment) will (ever) come: Even if I am brought back to my Lord, I shall surely find (there) something better in exchange."

(19) But your Lord is Most forgiving, full of Mercy. If He were to call them (at once) to account for what they have earned, then surely He would have hastened their punishment: but they have their appointed time, beyond which they will find no refuge.

(20) Then they proceeded: until, when they came to the inhabitants of a town, they asked them for food, but they refused them hospitality. They found there a wall on the point of falling down, but he set it up straight. (Moses) said: "If thou hadst wished, surely thou couldst have exacted some recompense for it!"
