Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever has wronged his (Muslim) brother with regard to his honor or anything else, let him seek forgiveness from him (in this world) before a day comes when there will be no dinar or dirham. If he has good deeds, they will be taken from him in proportion to his wrongdoing, and if he has no good deeds, the sins of the wronged person will be placed upon him." Narrated by al-Bukhari.
