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

(481) The likeness of the life of the present is as the rain which We send down from the skies: by its mingling arises the produce of the earth- which provides food for men and animals: (It grows) till the earth is clad with its golden ornaments and is decked out (in beauty): the people to whom it belongs think they have all powers of disposal over it: There reaches it Our command by night or by day, and We make it like a harvest clean-mown, as if it had not flourished only the day before! thus do We explain the Signs in detail for those who reflect.

(482) Say: "Who is it that sustains you (in life) from the sky and from the earth? or who is it that has power over hearing and sight? And who is it that brings out the living from the dead and the dead from the living? and who is it that rules and regulates all affairs?" They will soon say, "Allah". Say, "will ye not then show piety (to Him)?"

(483) Or do they say, "He forged it"? say: "Bring then a Sura like unto it, and call (to your aid) anyone you can besides Allah, if it be ye speak the truth!"

(484) if they charge thee with falsehood, say: "My work to me, and yours to you! ye are free from responsibility for what I do, and I for what ye do!"

(485) One day He will gather them together: (It will be) as if they had tarried but an hour of a day: they will recognise each other: assuredly those will be lost who denied the meeting with Allah and refused to receive true guidance.

(486) Whether We show thee (realised in thy life-time) some part of what We promise them,- or We take thy soul (to Our Mercy) (Before that),- in any case, to Us is their return: ultimately Allah is witness, to all that they do.

(487) They say: "When will this promise come to pass,- if ye speak the truth?"

(488) Say: "Do ye see,- if His punishment should come to you by night or by day,- what portion of it would the sinners wish to hasten?

(489) Every soul that hath sinned, if it possessed all that is on earth, would fain give it in ransom: They would declare (their) repentance when they see the penalty: but the judgment between them will be with justice, and no wrong will be done unto them.

(490) It is He Who giveth life and who taketh it, and to Him shall ye all be brought back.
