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

(1241) 'There are among us some that are righteous, and some the contrary; we are groups having different ways (religious sects).

(1242) if they (non-Muslims) had believed in Allah, and went on the Right Way (i.e. Islam) We would surely have bestowed on them water (rain) in abundance.

(1243) And when the slave of Allah (Muhammad صلى الله عليه وسلم) stood up invoking Him (his Lord - Allah) in prayer they (the jinn) just made round him a dense crowd as if sticking one over the other (in order to listen to the Prophet's recitation).

(1244) Say (O Muhammad صلى الله عليه وسلم): "None can protect me from Allah's punishment (if I were to disobey Him), nor can I find refuge except in Him.

(1245) And leave Me Alone to deal with the beliers (those who deny My Verses), those who are in possession of good things of life. And give them respite for a little while.

(1246) Then how can you avoid the punishment, if you disbelieve, on a Day (i.e. the Day of Resurrection) that will make the children grey-headed?

(1247) Verily, your Lord knows that you do stand (to pray at night) a little less than two thirds of the night, or half the night, or a third of the night, and also a party of those with you. And Allah measures the night and the day. He knows that you are unable to pray the whole night, so He has turned to you (in mercy). So, recite you of the Qur'an as much as may be easy for you. He knows that there will be some among you sick, others travelling through the land, seeking of Allah's Bounty, yet others fighting in Allah's Cause. So recite as much of the Qur'an as may be easy (for you), and perform As-Salat (Iqamat-as-Salat ) and give Zakat, and lend to Allah a goodly loan. And whatever good you send before you for yourselves (i.e. Nawafil non-obligatory acts of worship: prayers, charity, fasting, Hajj and 'Umrah), you will certainly find it with Allah, better and greater in reward. And seek Forgiveness of Allah. Verily, Allah is Oft-Forgiving, Most-Merciful .

(1248) And magnify your Lord (Allah)!

(1249) And purify your garments!

(1250) And made life smooth and comfortable for him.
