Abd al-Hamid bin Abs bin Jabr narrates from his father that Quraysh heard at night, on Mount Abu Qubays, the voice of a caller (an unseen voice) saying: "If the two Sa'ds accept Islam, Muhammad (peace and blessings be upon him) will rise in the morning in Makkah without any fear of the opposition of anyone who opposes him." When morning came, Abu Sufyan said: "Who are these two Sa'ds? Are they Sa'd bin Bakr and Sa'd bin Hudhaym?" When the second night came, they heard him saying again: "O Sa'd, Sa'd of the Aws (Sa'd bin Mu'adh), become a helper and supporter; and O Sa'd, Sa'd of the Khazraj with its noble chiefs (Sa'd bin Ubadah), you too answer the call. Respond to the one calling to guidance, and hope from Allah for that station in the Paradise of Firdaws which is the aim of one who truly knows. For the reward of Allah for the seeker of guidance is the gardens of Firdaws, full of greenery and green silk couches." When morning came, Abu Sufyan said: "By Allah, what is meant is Sa'd bin Mu'adh and Sa'd bin Ubadah (may Allah be pleased with them both)."
