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

(101) And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of Islamic Monotheism to mankind by inviting them to His religion of Islam), and has not laid upon you in religion any hardship: it is the religion of your father Ibrahim (Abraham) (Islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Qur'an), that the Messenger (Muhammad صلى الله عليه وسلم) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs]. He is your Maula (Patron, Lord), what an Excellent Maula (Patron, Lord) and what an Excellent Helper!

(102) Those who are faithfully true to their Amanat (all the duties which Allah has ordained, honesty, moral responsibility and trusts) and to their covenants;

(103) The only saying of the faithful believers, when they are called to Allah (His Words, the Qur'an) and His Messenger (صلى الله عليه وسلم), to judge between them, is that they say: "We hear and we obey." And such are the successful (who will live forever in Paradise).

(104) The true believers are only those, who believe in (the Oneness of) Allah and His Messenger (Muhammad صلى الله عليه وسلم): and when they are with him on some common matter, they go not away until they have asked his permission. Verily those who ask your permission, those are they who (really) believe in Allah and His Messenger. So if they ask your permission for some affairs of theirs, give permission to whom you will of them, and ask Allah for their forgiveness. Truly, Allah is Oft-Forgiving, Most Merciful.

(105) The dwellers of Paradise (i.e. those who deserved it through their Islamic Monotheistic faith and their deeds of righteousness) will, on that Day, have the best abode, and have the fairest of places for repose.

(106) Have you (O Muhammad صلى الله عليه وسلم) seen him who has taken as his ilah (god) his own vain desire? Would you then be a Wakil (a disposer of his affairs or a watcher) over him?

(107) And indeed We have distributed it (rain or water) amongst them in order that they may remember (the Grace of Allah,) but most men (refuse to accept the Truth or faith and) accept nothing but disbelief or ingratitude.

(108) And the (faithful) slaves of the Most Gracious (Allah) are those who walk on the earth in humility and sedateness, and when the foolish address them (with bad words) they reply back with mild words of gentleness.

(109) "So I fled from you when I feared you. But my Lord has granted me Hukm (i.e. religious knowledge, right judgement of the affairs and Prophethood), and made me one of the Messengers.

(110) My Lord! Bestow Hukm (religious knowledge, right judgement of the affairs and Prophethood) on me, and join me with the righteous.
