Abu Burdah bin Abi Musa al-Ash'ari (may Allah be pleased with him) said that Abdullah bin Umar (may Allah be pleased with them both) said: Do you know what my father said to your father? I said: No. He said: My father said to your father: O Abu Musa! Would it please you that our Islam with the Messenger of Allah (peace and blessings be upon him), our jihad with him (peace and blessings be upon him) and our every deed with him (peace and blessings be upon him) remain (secured for us), and that whatever deeds we did after him, we merely escape from them? Ibn Umar (may Allah be pleased with them both) said: Your father said to my father: By Allah! After the Messenger of Allah (peace and blessings be upon him) we waged jihad, we prayed, we fasted and we did a great many good deeds, and a great many people accepted Islam at our hands, and we hope (for reward) for that. My father said: But by the One in whose Hand is my soul! I wish that this would make our matter easy, and that whatever we did after him (peace and blessings be upon him), we merely escape through it. I said: By Allah! Your father was better than my father.
