Amr bin Maymun narrated the story of the killing of Sayyiduna Umar (may Allah be pleased with him) and said: Sayyiduna Umar (may Allah be pleased with him) said: O Abdullah! Look into my debt. They calculated it and it was eighty thousand, or close to that. Then Sayyiduna Umar (may Allah be pleased with him) said: If the wealth of the family of Umar is enough, then pay it off; otherwise ask among Banu Adi bin Ka'b, and if their wealth is not enough either, then ask among Quraysh, and do not go beyond them to anyone else, and pay off the debt on my behalf.
