Musannaf Ibn Abi Shaybah 34389 — Reports on al-Abbas

Amir said: The Prophet (peace and blessings be upon him) was setting out, and Sayyiduna al-Abbas (may Allah be pleased with him) was with him (peace and blessings be upon him). Sayyiduna al-Abbas (may Allah be pleased with him) was a man of sound judgement. The Prophet (peace and blessings be upon him) said: "O dear uncle, when you (may Allah be pleased with him) see something that would be of benefit to me, advise me to do it."
