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

(331) They say: "What is in the wombs of such and such cattle is specially reserved (for food) for our men, and forbidden to our women; but if it is still-born, then all have share therein. For their (false) attribution (of superstitions to Allah), He will soon punish them: for He is full of wisdom and knowledge.

(332) It is He Who produceth gardens, with trellises and without, and dates, and tilth with produce of all kinds, and olives and pomegranates, similar (in kind) and different (in variety): eat of their fruit in their season, but render the dues that are proper on the day that the harvest is gathered. But waste not by excess: for Allah loveth not the wasters.

(333) (Take) eight (head of cattle) in (four) pairs: of sheep a pair, and of goats a pair; say, hath He forbidden the two males, or the two females, or (the young) which the wombs of the two females enclose? Tell me with knowledge if ye are truthful:

(334) Say: "I find not in the message received by me by inspiration any (meat) forbidden to be eaten by one who wishes to eat it, unless it be dead meat, or blood poured forth, or the flesh of swine,- for it is an abomination - or, what is impious, (meat) on which a name has been invoked, other than Allah's". But (even so), if a person is forced by necessity, without wilful disobedience, nor transgressing due limits,- thy Lord is Oft-forgiving, Most Merciful.

(335) if they accuse thee of falsehood, say: "Your Lord is full of mercy all-embracing; but from people in guilt never will His wrath be turned back.

(336) Those who give partners (to Allah) will say: "if Allah had wished, we should not have given partners to Him nor would our fathers; nor should we have had any taboos." So did their ancestors argue falsely, until they tasted of Our wrath. Say: "Have ye any (certain) knowledge? if so, produce it before us. Ye follow nothing but conjecture: ye do nothing but lie."

(337) Say: "With Allah is the argument that reaches home: if it had been His will, He could indeed have guided you all."

(338) Say: "Bring forward your witnesses to prove that Allah did forbid so and so." if they bring such witnesses, be not thou amongst them: Nor follow thou the vain desires of such as treat our signs as falsehoods, and such as believe not in the Hereafter: for they hold others as equal with their Guardian-Lord.

(339) Say: "Come, I will rehearse what Allah hath (really) prohibited you from": Join not anything as equal with Him; be good to your parents; kill not your children on a plea of want;- We provide sustenance for you and for them;- come not nigh to shameful deeds. Whether open or secret; take not life, which Allah hath made sacred, except by way of justice and law: thus doth He command you, that ye may learn wisdom.

(340) And come not nigh to the orphan's property, except to improve it, until he attain the age of full strength; give measure and weight with (full) justice;- no burden do We place on any soul, but that which it can bear;- whenever ye speak, speak justly, even if a near relative is concerned; and fulfil the covenant of Allah: thus doth He command you, that ye may remember.
