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

(301) So eat of that (meat) on which Allah's Name has been pronounced (while slaughtering the animal), if you are believers in His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(302) Eat not (O believers) of that (meat) on which Allah's Name has not been pronounced (at the time of the slaughtering of the animal), for sure it is Fisq (a sin and disobedience of Allah). And certainly, the Shayatin (devils) do inspire their friends (from mankind) to dispute with you, and if you obey them [by making Al-Maitah (a dead animal) legal by eating it], then you would indeed be Mushrikun (polytheists); [because they (devils and their friends) made lawful to you to eat that which Allah has made unlawful to eat and you obeyed them by considering it lawful to eat, and by doing so you worshipped them; and to worship others besides Allah is polytheism].

(303) Is he who was dead (without Faith by ignorance and disbelief) and We gave him life (by knowledge and Faith) and set for him a light (of Belief) whereby he can walk amongst men - like him who is in the darkness (of disbelief, polytheism and hypocrisy) from which he can never come out? Thus it is made fair-seeming to the disbelievers that which they used to do.

(304) And whomsoever Allah wills to guide, He opens his breast to Islam; and whomsoever He wills to send astray, He makes his breast closed and constricted, as if he is climbing up to the sky. Thus Allah puts the wrath on those who believe not.

(305) O you assembly of jinn and mankind! "Did not there come to you Messengers from amongst you, reciting unto you My Verses and warning you of the meeting of this Day of yours?" They will say: "We bear witness against ourselves." It was the life of this world that deceived them. And they will bear witness against themselves that they were disbelievers.

(306) And your Lord is Rich (Free of all needs), full of Mercy; if He wills, He can destroy you, and in your place make whom He wills as your successors, as He raised you from the seed of other people.

(307) And so to many of the Mushrikun (polytheists - see V.2:105) their (Allah's so-called) "partners" have made fair-seeming the killing of their children, in order to lead them to their own destruction and cause confusion in their religion. And if Allah had willed, they would not have done so. So leave them alone with their fabrications.

(308) And they say: "What is in the bellies of such and such cattle (milk or foetus) is for our males alone, and forbidden to our females (girls and women), but if it is born dead, then all have shares therein." He will punish them for their attribution (of such false orders to Allah). Verily, He is All-Wise, All-Knower. (Tafsir At-Tabari).

(309) And it is He Who produces gardens trellised and untrellised, and date-palms, and crops of different shape and taste (their fruits and their seeds) and olives, and pomegranates, similar (in kind) and different (in taste). Eat of their fruit when they ripen, but pay the due thereof (its Zakat according to Allah's Orders 1/10th or 1/20th) on the day of its harvest, and waste not by extravagance . Verily, He likes not Al-Musrifun (those who waste by extravagance),

(310) Eight pairs: of the sheep two (male and female), and of the goats two (male and female). Say: "Has He forbidden the two males or the two females, or (the young) which the wombs of the two females enclose? Inform me with knowledge if you are truthful."
