The word(s) "if" appears 1640 time(s) in 1298 verse(s) in Quran in Mohsin Khan translation.

(1031) And from among His Signs are the night and the day, and the sun and the moon. Prostrate yourselves not to the sun nor to the moon, but prostrate yourselves to Allah Who created them, if you (really) worship Him.

(1032) But if they are too proud (to do so), then there are those who are with your Lord (angels) glorify Him night and day, and never are they tired.

(1033) And among His Signs (in this), that you see the earth barren; but when We send down water (rain) to it, it is stirred to life and growth (of vegetations). Verily, He Who gives it life, surely, is Able to give life to the dead (on the Day of Resurrection). Indeed He is Able to do all things.

(1034) Verily, those who disbelieved in the Reminder (i.e. the Qur'an) when it came to them (shall receive the punishment). And verily, it is an honourable well-fortified respected Book (because it is Allah's Speech, and He has protected it from corruption. (See V.15:9)

(1035) And if We had sent this as a Qur'an in a foreign language (other than Arabic), they would have said: "Why are not its verses explained in detail (in our language)? What! (A Book) not in Arabic and (the Messenger) an Arab?" Say: "It is for those who believe, a guide and a healing. And as for those who disbelieve, there is heaviness (deafness) in their ears, and it (the Qur'an) is blindness for them. They are those who are called from a place far away (so they neither listen nor understand)."

(1036) Man (the disbeliever) does not get tired of asking good (things from Allah); but if an evil touches him, then he gives up all hope and is lost in despair.

(1037) And truly, if We give him a taste of mercy from Us, after some adversity (severe poverty or disease, etc.) has touched him, he is sure to say: "This is due to my (merit); I think not that the Hour will be established. But if I am brought back to my Lord, surely, there will be for me the best (wealth) with Him. Then, We verily, will show to the disbelievers what they have done, and We shall make them taste a severe torment.

(1038) Say: "Tell me, if it (the Qur'an) is from Allah, and you disbelieve in it? Who is more astray than one who is in opposition far away (from Allah's Right Path and His obedience).

(1039) We will show them Our Signs in the universe, and in their own selves, until it becomes manifest to them that this (the Qur'an) is the truth. Is it not sufficient in regard to your Lord that He is a Witness over all things?

(1040) Nearly the heavens might be rent asunder from above them (by His Majesty): and the angels glorify the praises of their Lord, and ask for forgiveness for those on the earth. Verily, Allah is the Oft-Forgiving, the Most Merciful.
