Sahih al-Bukhari 7067

Abū ʿAwāna reported from ʿĀṣim, from Abū Wāʾil, from al-Ashʿarī, that he said to ʿAbd Allāh: “Do you know the days the Prophet, peace and blessings be upon him, mentioned—the days of al-harj?” The report is similar. Ibn Masʿūd said: “I heard the Prophet, peace and blessings be upon him, say: ‘Among the worst of people are those whom the Hour overtakes while they are still alive.’”
