Isma'il bin Ibrahim bin Aban said: I heard Ibn al-Munkadir narrating this hadith from Sayyiduna Abu Hurayrah (may Allah be pleased with him). He said: I was sitting in the shade with part of me in the sun, and when I heard it, I stood up. Ibn al-Munkadir said to me: "Sit down, there is no harm on you; you simply happened to sit like this."
