JABAL SAWR OR MOUNT OF THAWR
A mount in Makkah that the Prophet ﷺ hide in one of its caves during his migration to Al-Madeenah from Makkah.
It is mentioned in the Quran where Allaah The Almighty Says (what means): If you do not aid the Prophet - Allah has already aided him when those who disbelieved had driven him out [of Makkah] as one of two, when they were in the cave and he said to his companion, "Do not grieve; indeed Allah is with us." Quran Surah Tawbah 9:40 
Narrated Abu Bakr(R): Iwas in the company of the Prophet (ﷺ) in the cave, and on seeing the traces of the pagans, I said, "O Allah's Messenger (ﷺ) If one of them (pagans) should lift up his foot, he will see us." He said, "What do you think of two, the third of whom is Allah?" Vol. 6, Book 60, Hadith 185 (4709 and 3653) and Sahih Muslim 2381
