إِنَّ اللَّهَ يَأْمُرُكُمْ أَنْ تُؤَدُّوا الْأَمَانَاتِ إِلَى أَهْلِهَا
Allah commands you to deliver trusts to those entitled to them. (An-Nisāʾ 4:58)
Divine commands are conveyed to servants through the guidance given to Prophets and Messengers. Their mission is not merely the advocacy of personal virtues but the communication of Allah’s directions.
Being sent by Allah gives this instruction its religious authority.
