Ya'qub bin Ibrahim bin Sa'd narrates from his father, and he from his grandfather, that food was brought to Abd al-Rahman (may Allah be pleased with him), and he said: Mus'ab bin Umayr (may Allah be pleased with him) was killed, and nothing could be found in which to shroud him except a single cloak, and he was better than me; and Hamzah (may Allah be pleased with him), or another man, was martyred, and nothing could be found in which to shroud him except a single cloak.
