Jabal Tsur is a mountain in Saudi Arabia that is located in the lower part of Mecca. The place is popular among people belonging to the Islamic religion as it houses the well known Cave of Tsur.

According to Islamic legends, this cave is where the Holy Prophet and his companion Abu Bakr As-Siddiq found shelter when fleeing from Quraisy search parties. It is believed to be a sacred and holy site that was used as a hideout by Prophet Muhammad and his companions before his Hijrah (migration from Mecca to Medina), and took refuge here for three days and three nights.

It is believed that in order to protect the two of them from the searching troops, Allah had a spider weave a web at the cave entrance on the third day of their stay. The web prevented the soldiers from finding them, and thus, saved them from getting caught.

During this time, several miracles took place at the cave that reaffirmed the faith of the people of Islam in the benevolence of Allah.
