When Prophet Mohammad (SAW) and Abu Bakr (RA) reached mount Thawr during the migration to Medina, Abu Bakr (May Allah be pleased with him) carried him up the mountain to a cave called after the name of the mountain, Cave Thawr. Abu Bakr first entered to explore the cave and be sure that it was safe, closed all holes with pieces torn off from his clothes, cleaned it and then asked the Prophet (Peace be upon him) to step in. The Prophet (Peace be upon him) went in and immediately laid his head in Abu Bakr's lap and fell asleep. Suddenly Abu Bakr's foot was stung by a poisonous insect. It hurt so much that his tears fell on the Prophet's face. The Prophet (Peace be upon him) immediately applied his saliva on Abu Bakr's foot and the pain went off on the spot. They confined themselves to this cave for three nights, Friday, Saturday and Sunday. 'Abdullah, the son of Abu Bakr would go to see them after dusk, stay the night there, apprise them of the latest situation in Makkah, and then leave in the early morning to mix with the Makkans as usual and not to draw the least attention to his clandestine activities. 'Amir bin Fuhairah, while in the company of other shepherds of Makkah tending his master Abu Bakr's flock, used to stole away unobserved every evening with a few goats to the cave and furnished its inmates with a plentiful supply of milk.
