The word(s) "avail" appears 35 time(s) in 34 verse(s) in Quran in Mohsin Khan translation.

(1) And fear a Day (of Judgement) when a person shall not avail another, nor will intercession be accepted from him nor will compensation be taken from him nor will they be helped.

(2) And fear the Day (of Judgement) when no person shall avail another, nor shall compensation be accepted from him, nor shall intercession be of use to him, nor shall they be helped.

(3) O you who believe! When you contract a debt for a fixed period, write it down. Let a scribe write it down in justice between you. Let not the scribe refuse to write as Allah has taught him, so let him write. Let him (the debtor) who incurs the liability dictate, and he must fear Allah, his Lord, and diminish not anything of what he owes. But if the debtor is of poor understanding, or weak, or is unable to dictate for himself, then let his guardian dictate in justice. And get two witnesses out of your own men. And if there are not two men (available), then a man and two women, such as you agree for witnesses, so that if one of them (two women) errs, the other can remind her. And the witnesses should not refuse when they are called (for evidence). You should not become weary to write it (your contract), whether it be small or big, for its fixed term, that is more just with Allah; more solid as evidence, and more convenient to prevent doubts among yourselves, save when it is a present trade which you carry out on the spot among yourselves, then there is no sin on you if you do not write it down. But take witnesses whenever you make a commercial contract. Let neither scribe nor witness suffer any harm, but if you do (such harm), it would be wickedness in you. So be afraid of Allah; and Allah teaches you. And Allah is the All-Knower of each and everything.

(4) Verily, those who disbelieve, neither their properties nor their offspring will avail them whatsoever against Allah; and it is they who will be fuel of the Fire.

(5) Surely, those who reject Faith (disbelieve in Allah and in Muhammad صلى الله عليه وسلم) as being Allah's Messenger and in all that which he صلى الله عليه وسلم has brought from Allah), neither their properties, nor their offspring will avail them aught against Allah. They are the dwellers of the Fire, therein they will abide. (Tafsir At-Tabari).

(6) (O disbelievers) if you ask for a judgement, now has the judgement come unto you; and if you cease (to do wrong), it will be better for you, and if you return (to the attack), so shall We return, and your forces will be of no avail to you, however numerous they be; and verily, Allah is with the believers.

(7) Truly Allah has given you victory on many battle fields, and on the Day of Hunain (battle) when you rejoiced at your great number, but it availed you naught and the earth, vast as it is, was straitened for you, then you turned back in flight.

(8) Those who defame such of the believers who give charity (in Allah's Cause) voluntarily, and such who could not find to give charity (in Allah's Cause) except what is available to them - so they mock at them (believers); Allah will throw back their mockery on them, and they shall have a painful torment.

(9) And most of them follow nothing but conjecture. Certainly, conjecture can be of no avail against the truth. Surely, Allah is All-Aware of what they do.

(10) And he said: "O my sons! Do not enter by one gate, but enter by different gates, and I cannot avail you against Allah at all. Verily! The decision rests only with Allah. In Him, I put my trust and let all those that trust, put their trust in Him."
