Musannaf Ibn Abi Shayba 37:207

Abu Khalid al-Ahmar narrated to us, from ‘Amr ibn Qays, from a man, from Abu Dharr, who said: The Messenger of Allah (may Allah bless him and grant him peace) arrived from a journey. When he drew near to Medina, a group hastened toward their banners. He sent for them, and they were brought. He said, "What hastened you?" They said, "Did you not give us permission?" He said, "No, and I did not [intend/suggest] it, but you hastened toward the women in Medina." Then he said, "Oh, I wish I knew when a fire will emerge from the direction of Mount al-Waraq, the necks of the camels will be illuminated by it while kneeling, [reaching] as far as Barq al-Ghimad from ‘Adan Abyan, like the light of day."
