Mustadrak al-Hakim — Hadith 6080

It is narrated from Abu Burdah that Sayyiduna Ibn Umar (may Allah be pleased with them both) asked me: "Do you know what my father (Umar) said to your father (Abu Musa)?" I said: No. He said: My father asked your father: "Would it please you that our accepting Islam with the Messenger of Allah (peace and blessings be upon him), our emigration, our jihad and all our deeds remained secure for us, and that from every deed we did after that we would escape in such a way that we received neither reward nor sin (that is, came out even)?" Your father said to my father: "No, by Allah! After the Messenger of Allah (peace and blessings be upon him) we waged jihad, prayed, fasted and did much good, and we hope (from Allah) for its reward." Ibn Umar (may Allah be pleased with them both) says: At this my father said to your father: "By the One in Whose hand my soul is! My wish is that those early deeds remain secure for me, and that I escape from everything after that exactly even (so that no reckoning remains)." Abu Burdah says: I said (to Ibn Umar): "Indeed, your father was better than my father."
This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
