Musnad Ahmad 139:1

'Uthman ibn 'Umar narrated to us, he said: 'Abd al-Hamid ibn Ja'far narrated to us, Muhammad ibn 'Ali Abu Ja'far narrated to us, from Rafi' ibn Bishr—who is Abu Busr al-Sulami—from his father, that the Messenger of Allah, peace and blessings of Allah be upon him, said: "It is imminent that a fire will emerge from Habas Sayl. It will travel at the pace of slow camels. It will travel by day and halt by night. It will go out in the morning and return in the evening. It will be said: 'The fire has gone out in the morning, O people, so go out in the morning.' The fire will say: 'O people, so rest at midday.' 'The fire has returned in the evening, O people, so return in the evening.' Whoever it overtakes, it will consume."
