2.39. PROMISE AND TRUST (concluded)

God says

…And be true to every promise – for, verily, [on Judgment Day] you will be called to account for every promise which you have made!* -- Q.17:34

Verily We did offer the trust [of reason and violation] to the heavens, and the earth, and the mountains:* but they refused to bear it because they were afraid of it. Yet man took it up** – for, verily, he has always been prone to be most wicked, most foolish. -- Q.33:72
*Classical commentators give all kinds of laborious explanations to the term amanah (“trust”) occurring in this parable, but the most convincing of them ( mentioned in Lane 1, 102, with reference to the above verse) are “reason” or “intellect”, and the “faculty of volition”-- i.e., the ability to choose between two or more possible courses of action or modes of behaviour, and thus between good and evil.

** Sc., “and failed to measure up to the moral responsibility arising from the reason and the comparative free will with which he has been endowed” (Zamakhshari). This obviously applies to the human race as such, and not necessarily to all of its individuals.

.…and [those] who are faithful to their trusts and to their pledges; and who stand firm whenever they bear witness; -- Q.70: 32,33

Prophet said

3. “When a man passes an information and wants it to be kept a secret, it is a trust”– H: Tirmizi and Abu Daud. N: Jaber-b-Abdullah.

4. “Return the entrusted (article) to the one who entrusted (it), and do not betray one who betrayed you” – H: Tirmizi and Abu Daud. N: Abu Hurairah.

5. A trustworthy Muslim treasurer is one who carries out his duties honestly and issues what he is ordered to, and very happily hands it over in full to the person entitled to receive the same. Such a treasurer is like a person who himself donated something.” H: Bukhari and Muslim. N: Abu Musa Ash‘ari.
According to another Tradition, a person who hands over a thing to another person, as ordered, is also entitled to recompense of charity.
