In the name of Allah, the Most Merciful.
The Holy Quran 4:58:
Indeed, Allah commands you to render trusts to whom they are due and when you judge between people to judge with justice. Excellent is that which Allah instructs you. Indeed, Allah is ever Hearing and Seeing.
This ayat of Surah Nisa shows us the Sharia Law and Allah has bestowed Islam through Prophet Muhammad (PBUH) to all the nations. Allah has given from his Ilm-e-Kamil a way on how to spend life. One part of Islam is worshipping Allah and other part of Islam is society. If we would have embraced the rules of Islam, then perhaps it would be easy for non believers to come into the fold of Islam. A good society has a tendency to draw people in. People are in a wrong perception that Sharia law is just about punishing people.
We will be just looking at the first part of the ayat: "Indeed, Allah commands you to render trusts to whom they are due". The word trust used in this Surah is Amanat. The root meaning for Amanat in Arabic comes from ( ا م ن) meaning faith and trust and one who is trustworthy is called Amin. Amanat is the faith based on which a person gives something, tangible or intangible, to another for safekeeping under a definite and solid set of rules and conditions. It is one of the most accentuated qualities of a Muslim.
Prophet Muhammad (PBUH) was named as ‘As-Sadiq-ul-Amin’ for his trustworthiness even before declaring prophethood. Even non believers considered him trustworthy and would keep their property as Amanat to Him (PBUH). When Prophet Muhammad (PBUH) did Hijrah from Mecca to Madina he gave the belongings of people he had with instructions to Hazrat Ali (RZ) so that he can return them.
In Bukhari Book 2, Hadith 32: The Prophet (PBUH) said, "The signs of a hypocrite are three: 1. Whenever he speaks, he tells a lie. 2. Whenever he promises, he always breaks it (his promise ). 3. If you trust him, he proves to be dishonest. (If you keep something as a trust with him, he will not return it.)”
When Mahdi (AHS) was 4 years and 4 months old, Hazrat Khizr (AHS) gave Mahdi (AHS) the things that Prophet Muhammad (PBUH) kept as Amanat with Khizr (AHS). The Amanat was there with Khaja Khizr for more than 500 years and was intact with the command of Allah (SWT).
We are aware that betrayal of trusts results in fights, wars and even divorces. So how do make ourselves trustworthy? Trust begins by being honest (Sadiq) and not lying. There is a difference being Sadiq and being Amin. For being trustworthy (Amin) in addition to being honest, one needs to be responsible to hold their end of the deal which generally involves a form of action. Example, if it is as simple as being on time or to keep promises. This is how trust is built. Amongst the many qualities that blend together to make righteousness, is trustworthiness.
When you are given an opportunity to keep Amanat for someone, pray to Allah (SWT) for guidance that He helps you to keep your promises.
