Sayyiduna Abu Rafi' (may Allah be pleased with him) narrates that the Prophet of Allah (peace and blessings be upon him) sent Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) as an official to collect charity (zakah). He came to Sayyiduna al-Abbas bin Abd al-Muttalib (may Allah be pleased with him), and Sayyiduna al-Abbas (may Allah be pleased with him) spoke harshly to him. Sayyiduna Umar (may Allah be pleased with him) came to the Prophet (peace and blessings be upon him) and mentioned that to him (peace and blessings be upon him). So the Prophet (peace and blessings be upon him) said to him: "O Umar! Do you not know that a man's paternal uncle is like his father (of the same likeness and the same root)? And al-Abbas had already given us this year's charity in advance last year."
Imam al-Tabarani (may Allah have mercy on him) said: "Only Isma'il al-Makki narrated this hadith from Sulayman al-Ahwal, and only Sharik from Isma'il, and Ishaq al-Azraq is alone in narrating it."
