4-Surah An-Nisa ( The Women ) 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.
۞ إِنَّ اللَّهَ يَأْمُرُكُمْ أَن تُؤَدُّوا الْأَمَانَاتِ إِلَىٰ أَهْلِهَا وَإِذَا حَكَمْتُم بَيْنَ النَّاسِ أَن تَحْكُمُوا بِالْعَدْلِ ۚ إِنَّ اللَّهَ نِعِمَّا يَعِظُكُم بِهِ ۗ إِنَّ اللَّهَ كَانَ سَمِيعًا بَصِيرًا
Quran's Tafhim ( explanation)
*88). Here the Muslims are forewarned against the evils which had afflicted the Israelites. One of the fundamental mistakes committed by the Israelites was that in the time of their degeneration they had handed over positions of trust (i.e. religious and political leadership) to incompetent, mean, immoral, dishonest and corrupt people. The result was that corruption spread throughout the nation. The Muslims are directed to take heed of this, and to entrust positions of responsibility only to those who are capable of shouldering the burdens of such positions. The other major weakness of the Israelites was that they completely lost their sense of justice. In their pursuit of either personal or national interests, honesty and good faith were often sacrificed. The Muslims, in the time of the Prophet (peace be on him), were themselves subjected to gross injustice at their hands. On the one side were the Prophet (peace be on him) and his followers, to whose purity of life and conduct the Jews were themselves witnesses. On the other side were those who worshipped idols, buried their daughters alive, married their step-mothers and circumambulated the Ka'bah naked. Despite this, these so-called People of the Book felt no shame in declaring that the latter were closer to righteousness than the Muslims. After informing the Muslims of the iniquity of the Jews, God now warns them against committing similar injustices. They should rather declare what is right in the face of friend and foe alike, and judge between people with equity and justice.
