Abu al-‘Alā ibn ‘Umayr (may Allah be pleased with him) reported: I was with Qatādah ibn Milhān when he was in the throes of death. A man passed in a distant place in the house, so I saw him in the face of Qatādah. Whenever I saw him [in the past], his face as if had oil on it. The Messenger of Allah (may Allah's peace and blessings be upon him) had wiped over his face.
Abu al-‘Alā ibn ‘Umayr was in the presence of Qatādah ibn Milhān (may Allah be pleased with him) when death came upon him. A man passed in a distant place in the house, so Abu al-‘Alā saw him in the face of Qatādah, for his face was like a mirror. Whenever he saw him [in the past], his face was as if it was coated with oil, because it was clear, bright, and shiny. The Messenger of Allah (may Allah's peace and blessings be upon him) had wiped over the face of Qatādah. Hence, he earned such brightness and shininess because of the blessing of the Prophet wiping over his face.
