Hadith no. 1215 (below) is a repeat. Read it here.
Narrated Abu Wail:
Hudhaifa said, “‘Umar said, ‘Who amongst you remembers the statement of Allah’s Apostle (p.b.u.h) about afflictions’?’ I said, ‘I know it as the Prophet had said it.’ ‘Umar said, ‘No doubt, you are bold. How did he say it?’ I said, ‘A man’s afflictions (wrong deeds) concerning his wife, children and neighbors are expiated by (his) prayers, charity, and enjoining good.’ (The sub-narrator Sulaiman added that he said, ‘The prayer, charity, enjoining good and forbidding evil.’) ‘Umar said, ‘I did not mean that, but I ask about that affliction which will spread like the waves of the sea.’ I said, ‘O chief of the believers! You need not be afraid of it as there is a closed door between you and it.’ He asked, ‘Will the door be broken or opened?’ I replied, ‘No, it will be broken.’ He said, ‘Then, if it is broken, it will never be closed again?’ I replied, ‘Yes.’ ” Then we were afraid to ask what that door was, so we asked Masruq to inquire, and he asked Hudhaifa regarding it. Hudhaifa said, “The door was ‘Umar. “We further asked Hudhaifa whether ‘Umar knew what that door meant. Hudhaifa replied in the affirmative and added, “He knew it as one knows that there will be a night before the tomorrow morning.”
We get to know how a person gets all his past sins removed when he converts to Islam. That’s that. But what about the good that he used to do? Will he be rewarded for that or is that deleted as well along with the sins? Or does he get rewarded for it?
Narrated Hakim bin Hizam (radiallaahu `anhu):
I said to Allah’s Apostle (sallallaahu `alayhi wasallam), “Before embracing Islam I used to do good deeds like giving in charity, slave-manumitting, and the keeping of good relations with Kith and kin. Shall I be rewarded for those deeds?” The Prophet replied, “You became Muslim with all those good deeds (Without losing their reward).”
Awesome, right? That’s Mercy! Special mercy Allah bestows on His believing slaves. L.O.V.E.
