How did he, sallallaahu ‘alayhi wa sallam, judge between them

reported that he demanded the debt that Ibn Abu Hadrad (another Companion) owed him be paid back to him, and they raised their voices in the mosque, to the point that the Messenger of Allah, sallallaahu ‘alayhi wa sallam, heard them while he was in his home. He, sallallaahu ‘alayhi wa sallam, opened the curtain to his home (that overlooked the mosque), and said: “O Ka`b.” Ka`b replied: “I am at your service, O Messenger of Allah.” He, sallallaahu ‘alayhi wa sallam, said: “Reduce the debt he owes you,” and signaled with his hand in a manner that meant lower it half way. Ka`b said: “I have done so now, O Messenger of Allah.” Then he, sallallaahu ‘alayhi wa sallam, said (to Ibn Abu Hadrad): “Get up and pay off your debt.” Ibn Al-Jawzi (a scholar) said: “The Prophet’s, sallallaahu ‘alayhi wa sallam, order to him was an advice, and this shows that the judge has the right to persuade the two disputing parties on agreeing on a reconciliation, if he views that there is some sort of benefit in that.”
