The picture on the left shows Jabal Thawr mountain that contains the cave in which the Prophet (s.a.w.) and Abu Bakr (r.a.) sought refuge for three days and nights from the Quraysh, as they left Makkah and emigrated to Madinah.
Jabal Al-Thawr (mount bull) located towards the south of Misfilah district of Makkah. This mountain is house of Cave Al-Thaur (cave of bull). It is higher than Jabal Al-Noor, having a height of 1405m.
This mount and cave have a very high significance in the history of Islam regarding the great migration of Prophet صلى الله عليه وآله وسلم towards Madina.
This great migration took place from Abu Bakr's رضي الله عنه house in the darkness of night. When Prophet صلى الله عليه وآله وسلم and his beloved friend Abu Bakr رضي الله عنه) reached this mountain they stayed in here for three consecutive nights. Abu Bakr رضي الله عنه entered first and cleaned the cave and stuffed the holes with cloth so that no insect or reptile can harm the Prophet صلى الله عليه وآله وسلم. While the Prophet صلى الله عليه وآله وسلم slept on Abu Bakr's رضي الله عنه lap his foot was covering a bare hole, suddenly something stung his feet and the pain got worse. When Prophet woke up he saw that Abu Bakar رضي الله عنه was in immense pain, he applied his spittle on the injury and it disappeared.
Here they were kept updated with the activities of Quraish by Abu Bakar’s son Abdullah; who along with his servant Amir Bin Fuhayra رضي الله عنه stayed close whole night and returned to Makkah early morning followed by Amir so as to not let Quraish know of their acts. Amir bin Fuhayra رضي الله عنه; slave of Abu Bakr رضي الله عنه grazed the goats nearby to provide fresh milk to Abu Bakr رضي الله عنه and Prophet صلى الله عليه وآله وسلم.
The day when Quraish reached the mountain, Allah summoned a spider to build its web on the mouth of the cave so as to make it look old and deserted, also a pigeon was summoned to build its nest on that spider web and lay some eggs in it.
When search team of the Quraish reached the mouth of cave, they stood so close that Abu Bakr رضي الله عنه on seeing them became a little stressed about Prophet صلى الله عليه وآله وسلم being found. The Prophet صلى الله عليه وآله وسلم reassured him," How can you be apprehensive about two with whom is a third, especially when the third one is Allah?”
On finding spider's web and a nest in it on the mouth of the cave, the Quraish concluded that the cave was deserted. This whole scene is described in detail in Quran's Surah Tauba in these words:
“If ye help not (your leader), (it is no matter): for Allah did indeed help him, when the Unbelievers drove him out: he had no more than one companion; they two were in the cave, and he said to his companion, “Have no fear, for Allah is with us”: then Allah sent down His peace upon him, and strengthened him with forces which ye saw not, and humbled to the depths the word of the Unbelievers. But the word of Allah is exalted to the heights: for Allah is exalted in might, Wise."
When three days passed and the information came that the Quraish have stopped searching and have left the cave, both men started their journey towards Yasrib (Madina).
