Hadith.3243 - Al-Hasan ibn Mahbub narrated from Amr ibn Abi al-Miqdam, from his father, from Salamah ibn Kuhayl, from Commander of the Faithful Imam Ali ibn Abi Talib (as), who said to Shurayh: "O Shurayh, observe those who procrastinate, delay payments, oppress others, and deny people their rights despite having wealth and resources. Take the rights of the people from them and sell their properties and houses if necessary. I heard the Messenger of Allah (swt) (peace be upon him and his family) say: 'Delaying payment by a wealthy Muslim is injustice to another Muslim.' As for the one who has no wealth, property, or house, there is no recourse against him. Know that no one can enforce the truth upon people except one who restrains them from falsehood. Treat the Muslims equally in your appearance, speech, and seating so that your relatives do not hope for favoritism, nor do your enemies despair of your justice. Return the oath to the claimant along with evidence, for this is clearer for truth and firmer in judgment. Know that Muslims are trustworthy over one another, except for one who has been punished for a crime and has not repented, one who is known for false testimony, or one who is under suspicion. Beware of irritation and annoyance in the court, which Allah (swt) has made a place of reward and the best form of provision for those who judge with justice. Grant the claimant time to bring witnesses if they are absent. If he produces them, give him his right, and if not, decide the case against him. Beware of executing a judgment involving retaliation, legal punishments, or any right of Allah (swt), the Mighty and Majestic, without presenting it to me first. And do not sit in the court until you have eaten something, if Allah (swt) wills."
