It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) related from al-Ruh al-Amin (the Trustworthy Spirit, Jibril, peace be upon him) that the Lord, the Mighty and Majestic, said: "A servant's good deeds and bad deeds will be brought, and they will be settled (evened out) against one another; then, if even a single good deed remains, Allah will make room for him in Paradise." The narrator says: Then I went to Yazdad, and he also narrated the hadith in the same way. I asked him: What if the good deeds are used up (that is, the bad deeds equal them)? He said: Recite this verse: "Those are the ones from whom We accept the best of what they did and overlook their misdeeds, (they will be) among the companions of Paradise; a true promise which they had been promised." [Surah al-Ahqaf: 16] I asked him: What is your view of this saying of Allah Almighty: "No soul knows what joy for the eyes has been kept hidden for them as a reward for what they used to do" [Surah al-Sajdah: 17] ? He said: The deed a servant does in secret, of which people have no knowledge, its reward is upon Allah, the Mighty and Majestic; so on the Day of Resurrection Allah too will reveal for him a joy for the eyes that has been kept hidden (until then). This hadith has a sahih (authentic) chain of narration through the Yemeni narrators, but the two Shaykhs (Bukhari and Muslim) did not record it.
