Musannaf Ibn Abi Shaybah 34100 — Reports on Abu Bakr al-Siddiq

Al-Hasan (may Allah have mercy on him) said: The Prophet (peace and blessings be upon him) one day described Paradise and the blessings to be found in it. Then, speaking about it, he (peace and blessings be upon him) said: "Indeed, the birds found in it will be like Khurasani camels." Sayyiduna Abu Bakr (may Allah be pleased with him) said: "O Messenger of Allah (peace and blessings be upon him), those birds must surely be plump!" The Messenger of Allah (peace and blessings be upon him) said: "O Abu Bakr, whoever eats of them is more blessed than they are. By Allah, O Abu Bakr, I hope that you will be among those who eat of these birds."
