Verse Quran
2:282 O ye who believe! When ye deal with each other, in transactions involving future obligations in a fixed period of time, reduce them to writing Let a scribe write down faithfully as between the parties: let not the scribe refuse to write: as Allah Has taught him, so let him write. Let him who incurs the liability dictate, but let him fear His Lord Allah, and not diminish aught of what he owes. If they party liable is mentally deficient, or weak, or unable Himself to dictate, Let his guardian dictate faithfully, and get two witnesses, out of your own men, and if there are not two men, then a man and two women, such as ye choose, for witnesses, so that if one of them errs, the other can remind her. The witnesses should not refuse when they are called on (For evidence). Disdain not to reduce to writing (your contract) for a future period, whether it be small or big: it is juster in the sight of Allah, More suitable as evidence, and more convenient to prevent doubts among yourselves but if it be a transaction which ye carry out on the spot among yourselves, there is no blame on you if ye reduce it not to writing. But take witness whenever ye make a commercial contract; and let neither scribe nor witness suffer harm. If ye do (such harm), it would be wickedness in you. So fear Allah; For it is Good that teaches you. And Allah is well acquainted with all things. If ye are on a journey, and cannot find a scribe, a pledge with possession (may serve the purpose). And if one of you deposits a thing on trust with another, let the trustee (faithfully) discharge his trust, and let him Fear his Lord conceal not evidence; for whoever conceals it, - his heart is tainted with sin. And Allah knoweth all that ye do.
8:66 For the present, Allah hath lightened your (task), for He knoweth that there is a weak spot in you: But (even so), if there are a hundred of you, patient and persevering, they will vanquish two hundred, and if a thousand, they will vanquish two thousand, with the leave of Allah: for Allah is with those who patiently persevere.
30:54 It is Allah Who created you in a state of (helpless) weakness, then gave (you) strength after weakness, then, after strength, gave (you weakness and a hoary head: He creates as He wills, and it is He Who has all knowledge and power.
34:31 The Unbelievers say: "We shall neither believe in this scripture nor in (any) that (came) before it." Couldst thou but see when the wrong-doers will be made to stand before their Lord, throwing back the word (of blame) on one another! Those who had been despised will say to the arrogant ones: "Had it not been for you, we should certainly have been believers!"
34:32 The arrogant ones will say to those who had been despised: "Was it we who kept you back from Guidance after it reached you? Nay, rather, it was ye who transgressed.
34:33 Those who had been despised will say to the arrogant ones: "Nay! it was a plot (of yours) by day and by night: Behold! Ye (constantly) ordered us to be ungrateful to Allah and to attribute equals to Him!" They will declare (their) repentance when they see the Penalty: We shall put yokes on the necks of the Unbelievers: It would only be a requital for their (ill) Deeds.
