This is the cave in which Prophet Muhammed hid in as he made departure to Yathrib (now Medina) from Mecca while being pursued by Quraish of Mecca who were planning to harm him. According to traditions, once Muhammad and his companion made entrance into the cave, the entrance was blocked by a spider which had cast a web to cover it and gave the impression to members of Quraish that no one has made entrance inside the cave since a long time thus saved life of Muhammad. Today, many pilgrims climb up the 1,405 m high mountan to see the cave.
