The word(s) "surety" appears 13 time(s) in 13 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) Allah has promised, to those among you who believe and work righteous deeds, that He will, of a surety, grant them in the land, inheritance (of power), as He granted it to those before them; that He will establish in authority their religion - the one which He has chosen for them; and that He will change (their state), after the fear in which they (lived), to one of security and peace: 'They will worship Me (alone) and not associate aught with Me. 'If any do reject Faith after this, they are rebellious and wicked.

(12) They ask thee to hasten on the Punishment: but, of a surety, Hell will encompass the Rejecters of Faith!-

(13) Ask thou of them, which of them will stand surety for that!
