The word(s) "if" appears 1358 time(s) in 1110 verse(s) in Quran in Muhammad Habib Shakir translation.

(561) Say: if there were with Him gods as they say, then certainly they would have been able to seek a way to the Lord of power.

(562) The seven heavens declare His glory and the earth (too), and those who are in them; and there is not a single thing but glorifies Him with His praise, but you do not understand their glorification; surely He is Forbearing, Forgiving.

(563) Or some other creature of those which are too hard (to receive life) in your minds! But they will say: Who will return us? Say: Who created you at first. Still they will shake their heads at you and say: When will it be? Say: Maybe it has drawn nigh.

(564) Your Lord knows you best; He will have mercy on you if He pleases, or He will chastise you if He pleases; and We have not sent you as being in charge of them.

(565) And nothing could have hindered Us that We should send signs except that the ancients rejected them; and We gave to Samood the she-camel-- a manifest sign-- but on her account they did injustice, and We do not send signs but to make (men) fear.

(566) He said: Tell me, is this he whom Thou hast honored above me? if Thou shouldst respite me to the day of resurrection, I will most certainly cause his progeny to perish except a few.

(567) Your Lord is He Who speeds the ships for you in the sea that you may seek of His grace; surely He is ever Merciful to you.

(568) In that case We would certainly have made you to taste a double (punishment) in this life and a double (punishment) after death, then you would not have found any helper against Us.

(569) And if We please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us.

(570) Say: if men and jinn should combine together to bring the like of this Quran, they could not bring the like of it, though some of them were aiders of others.
