The word(s) "enough" appears 42 time(s) in 41 verse(s) in Quran in Abdullah Yusuf Ali translation.

(31) And Allah turned back the Unbelievers for (all) their fury: no advantage did they gain; and enough is Allah for the believers in their fight. And Allah is full of Strength, able to enforce His Will.

(32) (It is the practice of those) who preach the Messages of Allah, and fear Him, and fear none but Allah. And enough is Allah to call (men) to account.

(33) And obey not (the behests) of the Unbelievers and the Hypocrites, and heed not their annoyances, but put thy Trust in Allah. For enough is Allah as a Disposer of affairs.

(34) Therein will they cry aloud (for assistance): "Our Lord! Bring us out: we shall work righteousness, not the (deeds) we used to do!" - "Did We not give you long enough life so that he that would should receive admonition? and (moreover) the warner came to you. So taste ye (the fruits of your deeds): for the wrong-doers there is no helper."

(35) Is not Allah enough for his Servant? But they try to frighten thee with other (gods) besides Him! for such as Allah leaves to stray, there can be no guide.

(36) Soon will We show them our Signs in the (furthest) regions (of the earth), and in their own souls, until it becomes manifest to them that this is the Truth. Is it not enough that thy Lord doth witness all things?

(37) Or do they say, "He has forged it"? Say: "Had I forged it, then can ye obtain no single (blessing) for me from Allah. He knows best of that whereof ye talk (so glibly)! enough is He for a witness between me and you! And he is Oft-Forgiving, Most Merciful."

(38) It is He Who has sent His Messenger with Guidance and the Religion of Truth, to proclaim it over all religion: and enough is Allah for a Witness.

(39) There have already come to them Recitals wherein there is (enough) to check (them),

(40) Turnest thou not thy sight towards those who were forbidden secret counsels yet revert to that which they were forbidden (to do)? And they hold secret counsels among themselves for iniquity and hostility, and disobedience to the Messenger. And when they come to thee, they salute thee, not as Allah salutes thee, (but in crooked ways): And they say to themselves, "Why does not Allah punish us for our words?" enough for them is Hell: In it will they burn, and evil is that destination!
