The word(s) "fai" appears 219 time(s) in 200 verse(s) in Quran in Mohsin Khan translation.

(51) You killed them not, but Allah killed them. And you (Muhammad صلى الله عليه وسلم) threw not when you did throw, but Allah threw, that He might test the believers by a fair trial from Him. Verily, Allah is All-Hearer, All-Knower.

(52) (And remember) when you (the Muslim army) were on the near side of the valley, and they on the farther side, and the caravan on the ground lower than you. Even if you had made a mutual appointment to meet, you would certainly have failed in the appointment, but (you met) that Allah might accomplish a matter already ordained (in His Knowledge), so that those who were to be destroyed (for their rejecting the faith) might be destroyed after a clear evidence, and those who were to live (i.e. believers) might live after a clear evidence. And surely, Allah is All-Hearer, All-Knower.

(53) And (remember) when Shaitan (Satan) made their (evil) deeds seem fair to them and said, "No one of mankind can overcome you this Day (of the battle of Badr) and verily, I am your neighbour (for each and every help)." But when the two forces came in sight of each other, he ran away and said "Verily, I have nothing to do with you. Verily! I see what you see not. Verily! I fear Allah for Allah is Severe in punishment."

(54) Except those of the Mushrikun (see V.2:105) with whom you have a treaty, and who have not subsequently failed you in aught, nor have supported anyone against you. So fulfil their treaty to them for the end of their term. Surely Allah loves Al-Mattaqun (the pious - See V.2:2).

(55) The postponing (of a Sacred Month) is indeed an addition to disbelief: thereby the disbelievers are led astray, for they make it lawful one year and forbid it another year in order to adjust the number of months forbidden by Allah, and make such forbidden ones lawful. The evil of their deeds is made fair-seeming to them. And Allah guides not the people who disbelieve.

(56) And among them are men who annoy the Prophet (Muhammad صلى الله عليه وسلم) and say: "He is (lending his) ear (to every news)." Say: "He listens to what is best for you; he believes in Allah, has faith in the believers, and is a mercy to those of you who believe." But those who annoy Allah's Messenger (Muhammad صلى الله عليه وسلم) will have a painful torment. [See V.33:57]

(57) And the foremost to embrace Islam of the Muhajirun (those who migrated from Makkah to Al-Madinah) and the Ansar (the citizens of Al-Madinah who helped and gave aid to the Muhajirun ) and also those who followed them exactly (in faith). Allah is well-pleased with them as they are well-pleased with Him. He has prepared for them Gardens under which rivers flow (Paradise), to dwell therein forever. That is the supreme success.

(58) And whenever there comes down a Surah (chapter from the Qur'an), some of them (hypocrites) say: "Which of you has had his faith increased by it?" As for those who believe, it has increased their faith, and they rejoice.

(59) Surely, your Lord is Allah Who created the heavens and the earth in six Days and then rose over (Istawa ) the Throne (really in a manner that suits His Majesty), disposing the affair of all things. No intercessor (can plead with Him) except after His Leave. That is Allah, your Lord; so worship Him (Alone). Then, will you not remember?

(60) Verily, those who believe, and do deeds of righteousness, their Lord will guide them through their faith; under them will flow rivers in the Gardens of Delight (Paradise).
