Episode #13 informs us of the function of the angel when people remain just and fair when judging a dispute.
The prophet s.aw. said that when a person is asked to judge and they do it righteously Allah s.w.t sends angels who guide them to the truth.
There is a story of Omar Al Khattab who had to judge a dispute between a Muslim and a Jew. The Khalifah judged in favour of the Jew over the Muslim and the Jew said that Omar had judged correctly. Omar wanted to know how the Jew knew this.
Listen to the end of this brief talk to discover the Jew’s reply to the honourable Khalifah.
