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

(31) And they say, "None shall enter Paradise unless he be a Jew or a Christian." These are their own desires. Say (O Muhammad صلى الله عليه وسلم), "Produce your proof if you are truthful."

(32) The Jews said that the Christians follow nothing (i.e. are not on the right religion); and the Christians said that the Jews follow nothing (i.e. are not on the right religion); though they both recite the Scripture. Like unto their word, said (the pagans) who know not. Allah will judge between them on the Day of Resurrection about that wherein they have been differing.

(33) And who are more unjust than those who forbid that Allah's Name be glorified and mentioned much (i.e. prayers and invocations, etc.) in Allah's Mosques and strive for their ruin? It was not fitting that such should themselves enter them (Allah's Mosques) except in fear. For them there is disgrace in this world, and they will have a great torment in the Hereafter.

(34) Never will the Jews nor the Christians be pleased with you (O Muhammad صلى الله عليه وسلم) till you follow their religion. Say: "Verily, the Guidance of Allah (i.e. Islamic Monotheism) that is the (only) Guidance. And if you (O Muhammad صلى الله عليه وسلم) were to follow their (Jews and Christians) desires after what you have received of Knowledge (i.e. the Qur'an), then you would have against Allah neither any Wali (protector or guardian) nor any helper.

(35) And (remember) when We made the House (the Ka'bah at Makkah) a place of resort for mankind and a place of safety. And take you (people) the Maqam (place) of Ibrahim (Abraham) [or the stone on which Ibrahim (Abraham) عليه السلام stood while he was building the Ka'bah] as a place of prayer (for some of your prayers, e.g. two Rak'at after the Tawaf of the Ka'bahat Makkah), and We commanded Ibrahim (Abraham) and Isma'il (Ishmael) that they should purify My House (the Ka'bah at Makkah) for those who are circumambulating it, or staying (I'tikaf), or bowing or prostrating themselves (there, in prayer).

(36) Our Lord! And make us submissive unto You and of our offspring a nation submissive unto You, and show us our Manasik (all the ceremonies of pilgrimage - Hajjand 'Umrah), and accept our repentance. Truly, You are the One Who accepts repentance, the Most Merciful.

(37) Our Lord! Send amongst them a Messenger of their own (and indeed Allah answered their invocation by sending Muhammad صلى الله عليه وسلم), who shall recite unto them Your Verses and instruct them in the Book (this Qur'an) and Al-Hikmah (full knowledge of the Islamic laws and jurisprudence or wisdom or Prophethood), and purify them. Verily! You are the All-Mighty, the All-Wise."

(38) And they say, "Be Jews or Christians, then you will be guided." Say (to them O Muhammad صلى الله عليه وسلم), "Nay, (we follow) only the religion of Ibrahim (Abraham), Hanifa [Islamic Monotheism, i.e. to worship none but Allah (Alone)], and he was not of Al-Mushrikun (those who worshipped others along with Allah - see V.2:105)."

(39) So if they believe in the like of that which you believe, then they are rightly guided; but if they turn away, then they are only in opposition. So Allah will suffice you against them. And He is the All-Hearer, the All-Knower.

(40) Thus We have made you [true Muslims - real believers of Islamic Monotheism, true followers of Prophet Muhammad صلى الله عليه وسلم and his Sunnah (legal ways)], a just (and the best) nation, that you be witnesses over mankind and the Messenger (Muhammad صلى الله عليه وسلم) be a witness over you. And We made the Qiblah (prayer direction towards Jerusalem) which you used to face, only to test those who followed the Messenger (Muhammad صلى الله عليه وسلم) from those who would turn on their heels (i.e. disobey the Messenger). Indeed it was great (heavy) except for those whom Allah guided. And Allah would never make your faith (prayers) to be lost (i.e. your prayers offered towards Jerusalem). Truly, Allah is full of Kindness, the Most Merciful towards mankind.
