Musnad Ahmad Hadith 3603

The believer sees his sins as being like the bottom of a mountain that he fears will fall on him; the evildoer sees his sins as being like flies that land on his nose, and he does this and they fly away. He said: And the Messenger of Allah (ﷺ) said: "Verily, Allah rejoices more over the repentance of His believing slave than a man who goes out in a desolate land and has his mount with him, on which is his food and drink and provisions and all that he needs, then he loses it, so he goes out looking for it until he is about to die and has not found it, so he says to himself: I will go back to the place where I lost it, and die there. He goes back to that place and falls asleep, then he wakes up and there is his mount, standing at his head, with his food and drink and provisions and all that he needs on it.”
