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

(71) (The King) said (to the women): "What was your affair when you did seek to seduce Yusuf (Joseph)?" The women said: "Allah forbid! No evil know we against him!" The wife of Al-'Aziz said: "Now the truth is manifest (to all); it was I who sought to seduce him, and he is surely of the truthful."

(72) So, when they despaired of him, they held a conference in private. The eldest among them said: "Know you not that your father did take an oath from you in Allah's Name, and before this you did fail in your duty with Yusuf (Joseph)? Therefore I will not leave this land until my father permits me, or Allah decides my case (by releasing Benjamin) and He is the Best of the judges.

(73) Allah is He Who raised the heavens without any pillars that you can see. Then, He rose above (Istawa) the Throne (really in a manner that suits His Majesty). He has subjected the sun and the moon (to continue going round), each running (its course) for a term appointed. He manages and regulates all affairs; He explains the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) in detail, that you may believe with certainty in the meeting with your Lord.

(74) Is then He (Allah) Who takes charge (guards, maintains, provides) of every person and knows all that he has earned (like any other deities who know nothing)? Yet, they ascribe partners to Allah. Say: "Name them! Is it that you will inform Him of something He knows not in the earth or is it (just) a show of false words." Nay! To those who disbelieved, their plotting is made fairseeming, and they have been hindered from the Right Path; and whom Allah sends astray, for him there is no guide.

(75) And (remember) when your Lord proclaimed: "If you give thanks (by accepting faith and worshipping none but Allah), I will give you more (of My Blessings); but if you are thankless (i.e. disbelievers), verily My punishment is indeed severe."

(76) So think not that Allah will fail to keep His Promise to His Messengers. Certainly, Allah is All-Mighty, All-Able of Retribution.

(77) Your Ilah (God) is One Ilah (God - Allah, none has the right to be worshipped but He). But for those who believe not in the Hereafter, their hearts deny (the faith in the Oneness of Allah), and they are proud.

(78) By Allah, We indeed sent (Messengers) to the nations before you (O Muhammad صلى الله عليه و سلم), but Shaitan (Satan) made their deeds fair-seeming to them. So he (Satan) is their Wali (helper) today (i.e. in this world), and theirs will be a painful torment.

(79) Say (O Muhammad صلى الله عليه و سلم) Ruh-ul-Qudus [Jibril (Gabriel)] has brought it (the Qur'an) down from your Lord with truth, that it may make firm and strengthen (the faith of) those who believe, and as a guidance and glad tidings to those who have submitted (to Allah as Muslims).

(80) Whoever disbelieved in Allah after his belief, except him who is forced thereto and whose heart is at rest with faith; but such as open their breasts to disbelief, on them is wrath from Allah, and theirs will be a great torment.
