Cave of Thaur
Hajj. The cave is famously versed in the Holy Quran, where the Holy Prophet (pbuh) was ordered to leave Makkah by Allah to escape from the threat of his enemies. Abu Bakr went along with him and they both hid in this particular cave for three days and three nights.
While hiding from their enemies who approached closer to the cave, a tree grew in front of the entrance of the cave covering it; while a bird made a nest and laid her eggs; and a spider spun its web on the entrance of the cave, all done by the order of Allah (swt). This was referred to as the miracle of the cave and caused the enemies to disregard the cave as a place of hiding for the Prophet. Professional trackers were hired and one of the best trackers, Abu Karz, traced the footprints of the Prophet up to the cave. However, as they neared the cave, they argued that if anyone had entered it, the web and the eggs would have been broken, but since both were intact, no one had entered it. As the enemies drew near, in search of the Holy Prophet, Abu Bakr got very distressed and started to grieve. The following verse from Surah at-Tawbah speaks of the incident:
[9:40] If ye help him not, still Allah helped him when those who disbelieve drove him forth, the second of two; when they two were in the cave, when he said unto his comrade: Grieve not. Lo! Allah is with us. Then Allah caused His peace of reassurance to descend upon him and supported him with hosts ye cannot see, and made the word of those who disbelieved the nethermost, while Allah's Word it was that became the uppermost. Allah is Mighty, Wise.
On the fourth day, the Prophet (pbuh) along with Abu Bakr and a reliable guide by the name of Abdullah ibn Urayqit al-Daylami, initiated their journey towards Medina.
