It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever offers an apology to his brother and he does not accept his excuse, upon him will be a sin like the sin of one who collects unlawful levies." Abu al-Zubayr (may Allah have mercy on him) said: "Al-makkas means al-'ashshar (the collector of tolls)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abu al-Zubayr except Abu Amr al-Abdi, and no one from Abu Amr except Ibrahim bin A'yan; Layth is alone in narrating it."
