Musannaf Ibn Abi Shaybah 37748 — Khaythamah bin Abd al-Rahman

It is narrated from Isma'il bin Abi Khalid that he said: I heard Khaythamah speaking about the saying of Allah {a Day that will turn children white-haired} [Al-Muzzammil: 17]. He said: On the Day of Resurrection a caller will call out: "Let those deserving of Hell come forth: out of every 1000, 999." It is because of this that children will turn white-haired.
