Hadith 11:39
'Isa narrated to us, from al-Awza'i, from Hassan ibn 'Atiyyah, who said: "Whoever spends the night as a guard, guarding for a night, he wakes up having had his sins shed away." Al-Awza'i said: Makhul said: "He spends the night until he wakes up, and his sins are shed away from him."
حدثنا عيسى عن الأوزاعي عن حسان بن عطية قال من بات حارسا حرس ليلة أصبح وقد تحاتت خطاياه قال الأوزاعي قال مكحول بات حتى يصبح تحاتت عنه خطاياه
