The word(s) "necessarily" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Gardens of Eternity, those which (Allah) Most Gracious has promised to His servants in the Unseen: for His promise must (necessarily) come to pass.

(2) Had it not been for a Word that went forth before from thy Lord, (their punishment) must necessarily have come; but there is a Term appointed (for respite).

(3) Thou wilt see the Wrong-doers in fear on account of what they have earned, and (the burden of) that must (necessarily) fall on them. But those who believe and work righteous deeds will be in the luxuriant meads of the Gardens: they shall have, before their Lord, all that they wish for. That will indeed be the magnificent Bounty (of Allah).
