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

(11) And He taught Adam all the names (of everything) , then He showed them to the angels and said, "Tell Me the names of these if you are truthful."

(12) And We said: "O Adam! Dwell you and your wife in the Paradise and eat both of you freely with pleasure and delight, of things therein as wherever you will, but come not near this tree or you both will be of the Zalimun (wrong-doers)."

(13) Then Adam received from his Lord Words. And his Lord pardoned him (accepted his repentance). Verily, He is the One Who forgives (accepts repentance), the Most Merciful.

(14) And (remember) when Musa (Moses) said to his people: "O my people! Verily, you have wronged yourselves by worshipping the calf. So turn in repentance to your Creator and kill yourselves (the innocent kill the wrongdoers among you), that will be better for you with your Creator." Then He accepted your repentance. Truly, He is the One Who accepts repentance, the Most Merciful.

(15) And (remember) when We said: "Enter this town (Jerusalem) and eat bountifully therein with pleasure and delight wherever you wish, and enter the gate in prostration (or bowing with humility) and say: 'Forgive us,' and We shall forgive you your sins and shall increase (reward) for the good-doers."

(16) They said, "Call upon your Lord for us to make plain to us what it is. Verily, to us all cows are alike. And surely, if Allah wills, we will be guided."

(17) So We said: "Strike him (the dead man) with a piece of it (the cow)." Thus Allah brings the dead to life and shows you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) so that you may understand.

(18) And (remember) when We took a covenant from the Children of Israel, (saying): Worship none but Allah (Alone) and be dutiful and good to parents, and to kindred, and to orphans and Al-Masakin (the poor), and speak good to people [i.e. enjoin righteousness and forbid evil, and say the truth about Muhammad صلى الله عليه وسلم], and perform As-Salat (Iqamat-as-Salat), and give Zakat. Then you slid back, except a few of you, while you are backsliders. (Tafsir Al-Qurtubi).

(19) And (remember) when We took your covenant (saying): Shed not the blood of your (people), nor turn out your own people from their dwellings. Then, (this) you ratified and (to this) you bear witness.

(20) After this, it is you who kill one another and drive out a party of you from their homes, assist (their enemies) against them, in sin and transgression. And if they come to you as captives, you ransom them, although their expulsion was forbidden to you. Then do you believe in a part of the Scripture and reject the rest? Then what is the recompense of those who do so among you, except disgrace in the life of this world, and on the Day of Resurrection they shall be consigned to the most grievous torment. And Allah is not unaware of what you do.
