Sahih al-Bukhari Hadith 3915

Narrated Abu Burda Bin Abi Musa Al-Ash`ari: `Abdullah bin `Umar said to me, "Do you know what my father said to your father once?" I said, "No." He said, "My father said to your father, 'O Abu Musa, will it please you that we will be rewarded for our conversion to Islam with Allah's Messenger (ﷺ) and our migration with him, and our Jihad with him and all our good deeds which we did, with him, and that all the deeds we did after his death will be disregarded whether good or bad?' Your father (i.e. Abu Musa) said, 'No, by Allah, we took part in Jihad after Allah's Messenger (ﷺ) , prayed and did plenty of good deeds, and many people have embraced Islam at our hands, and no doubt, we expect rewards from Allah for these good deeds.' On that my father (i.e. `Umar) said, 'As for myself, By Him in Whose Hand `Umar's soul is, I wish that the deeds done by us at the time of the Prophet (ﷺ) remain rewardable while whatsoever we did after the death of the Prophet (ﷺ) be enough to save us from Punishment in that the good deeds compensate for the bad ones.' " On that I said (to Ibn `Umar), "By Allah, your father was better than my father!"
