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

(571) And He gave you of all that you asked for, and if you count the Blessings of Allah, never will you be able to count them. Verily, man is indeed an extreme wrong-doer, a disbeliever (an extreme ingrate who denies Allah's Blessings by disbelief, and by worshipping others besides Allah, and by disobeying Allah and His Prophet Muhammad صلى الله عليه و سلم).

(572) "O my Lord! They have indeed led astray many among mankind. But whoso follows me, he verily is of me. And whoso disobeys me, still You are indeed Oft-Forgiving, Most Merciful.

(573) That Allah may requite each person according to what he has earned. Truly, Allah is Swift at reckoning.

(574) Alif-Lam-Ra. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings].These are Verses of the Book and a plain Qur'an.

(575) "Why do you not bring angels to us if you are of the truthful?"

(576) And even if We opened to them a gate from the heaven and they were to keep on ascending thereto (all the day long)

(577) They would surely say (in the evening): "Our eyes have been (as if) dazzled (we have not seen any angel or heaven). Nay, we are a people bewitched."

(578) And indeed, We have put the big stars in the heaven and We beautified it for the beholders.

(579) And certainly We! We it is Who give life, and cause death, and We are the Inheritors.

(580) Declare (O Muhammad صلى الله عليه و سلم) unto My slaves, that truly, I am the Oft-Forgiving, the Most-Merciful.
