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

(21) "But we can surely produce magic to match thine! So make a tryst between us and thee, which we shall not fail to keep - neither we nor thou - in a place where both shall have even chances."

(22) (Pharaoh) said: "Believe ye in Him before I give you permission? surely this must be your leader, who has taught you magic! be sure I will cut off your hands and feet on opposite sides, and I will have you crucified on trunks of palm-trees: so shall ye know for certain, which of us can give the more severe and the more lasting punishment!"

(23) If it had been Our wish to take (just) a pastime, We should surely have taken it from the things nearest to Us, if We would do (such a thing)!

(24) So they turned to themselves and said, "surely ye are the ones in the wrong!"

(25) Verily ye, (unbelievers), and the (false) gods that ye worship besides Allah, are (but) fuel for Hell! to it will ye (surely) come!

(26) (They are) those who have been expelled from their homes in defiance of right,- (for no cause) except that they say, "our Lord is Allah". Did not Allah check one set of people by means of another, there would surely have been pulled down monasteries, churches, synagogues, and mosques, in which the name of Allah is commemorated in abundant measure. Allah will certainly aid those who aid his (cause);- for verily Allah is full of Strength, Exalted in Might, (able to enforce His Will).

(27) Said (Pharaoh): "Believe ye in Him before I give you permission? surely he is your leader, who has taught you sorcery! but soon shall ye know! Be sure I will cut off your hands and your feet on opposite sides, and I will cause you all to die on the cross!"

(28) By inspiration we told Moses: "Travel by night with my servants; for surely ye shall be pursued."

(29) For those whose hopes are in the meeting with Allah (in the Hereafter, let them strive); for the term (appointed) by Allah is surely coming and He hears and knows (all things).

(30) And yet they had already covenanted with Allah not to turn their backs, and a covenant with Allah must (surely) be answered for.
