Mishkat al-Masabih 2096

Anas reported God's messenger as saying that when lailat al-qadr comes Gabriel descends with a company of angels who invoke blessings on everyone who is standing or sitting and remembering God who is great and glorious. Then when their festival day comes, i.e. the day when they break their fast, God speaks proudly of them to His angels saying, “My angels, what is the reward of a hired servant who has fully accomplished his work?” They reply, “Our Lord, his reward is that he should be paid his wage in full.” He says, “My angels, my male and female servants have fulfilled what I have made obligatory for them, and then have come out raising their voices in supplication. By my might, glory, honour, high dignity, and exalted station, I will certainly answer them.” Then He says, “Return, for I have forgiven you and changed your evil deeds into good deeds.” He said that they then return having received forgiveness. Baihaqi transmitted it in Shu'ab al-iman.
