It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Woe to the rich on the Day of Resurrection because of the poor! They will say (before Allah): 'Our Lord! These people wronged us regarding our rights which You made obligatory upon them for us.' Allah, the Mighty and Majestic, will say: 'By My Might and My Majesty! I will surely bring you near (to Me) and I will surely drive them far away (from Me).'" Then the Messenger of Allah (peace and blessings be upon him) recited this verse: "And those in whose wealth there is a known right for the one who asks and the one who is deprived."
No one narrated this hadith from Sayyiduna Anas (may Allah be pleased with him) except Harith bin al-Nu'man (may Allah have mercy on him).
