The word(s) "if" appears 1620 time(s) in 1267 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1211) The Day whereon they will issue from their sepulchres in sudden haste as if they were rushing to a goal-post (fixed for them),-

(1212) "So He may forgive you your sins and give you respite for a stated Term: for when the Term given by Allah is accomplished, it cannot be put forward: if ye only knew."

(1213) "For, if Thou dost leave (any of) them, they will but mislead Thy devotees, and they will breed none but wicked ungrateful ones.

(1214) 'And Exalted is the Majesty of our Lord: He has taken neither a wife nor a son.

(1215) (And Allah's Message is): "if they (the Pagans) had (only) remained on the (right) Way, We should certainly have bestowed on them Rain in abundance.

(1216) "That We might try them by that (means). But if any turns away from the remembrance of his Lord, He will cause him to undergo a severe Penalty.

(1217) Say: "No one can deliver me from Allah (if I were to disobey Him), nor should I find refuge except in Him,

(1218) And leave Me (alone to deal with) those in possession of the good things of life, who (yet) deny the Truth; and bear with them for a little while.

(1219) Then how shall ye, if ye deny (Allah), guard yourselves against a Day that will make children hoary-headed?-

(1220) Thy Lord doth know that thou standest forth (to prayer) nigh two-thirds of the night, or half the night, or a third of the night, and so doth a party of those with thee. But Allah doth appoint night and day in due measure He knoweth that ye are unable to keep count thereof. So He hath turned to you (in mercy): read ye, therefore, of the Qur'an as much as may be easy for you. He knoweth that there may be (some) among you in ill-health; others travelling through the land, seeking of Allah's bounty; yet others fighting in Allah's Cause, read ye, therefore, as much of the Qur'an as may be easy (for you); and establish regular Prayer and give regular Charity; and loan to Allah a Beautiful Loan. And whatever good ye send forth for your souls ye shall find it in Allah's Presence,- yea, better and greater, in Reward and seek ye the Grace of Allah: for Allah is Oft-Forgiving, Most Merciful.
