The Hour will not be established until a fire comes out of the land of Hejaz and throws light on the necks of camels in Busra
Authentic hadithعن أبي هريرة رضي الله عنه مرفوعًا: «لا تقومُ الساعةُ حتى تخرجَ نارٌ من أرض الحِجاز تُضيءُ أعناقَ الإبل ببُصْرى».
Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "The Hour will not be established until a fire comes out of the land of Hejaz and throws light on the necks of camels in Busra."
Explanation
The Hour will not be established until a fire comes out of Makkah, Madīnah, and the surrounding area. It will illuminate the necks of camels in the city of Busra in Sham. In the year 654 A.H., a fire came out in Madīnah, and it was a great fire that came out from the eastern side of Madīnah behind Al-Harrah. All the people of the Levant and all other lands learned about that fire. Contemporary scholars at that time, like An-Nawawi, Al-Qurtubi, and Abu Shāmah, mentioned it in their books.
