MIGRATION OF THE PROPHET (Peace be upon him) :
When the iniquitous decision had been made, Gabriel was sent down to Muhammad (Peace be upon  him) to reveal to him Quraish’s plot and give him his Lord’s Permission to leave Makkah. He fixed to  him the time of migration and asked him not to sleep that night in his usual bed. At noon, the Prophet
(Peace be upon him) went to see his Companion Abu Bakr and arranged with him everything for the  intended migration. Abu Bakr was surprised to see the Prophet (Peace be upon him) masked coming  to  visit him at that unusual time, but he soon learned that Allâh’s Command had arrived, and he  proposed  that they should migrate together, to which the Prophet (Peace be upon him) gave his consent.
To make the necessary preparations for the implementation of their devilish plan, the chiefs of Makkah  had chosen eleven men: Abu Jahl, Hakam bin Abil Al-‘As, ‘Uqbah bin Abi Mu‘ait, An-Nadr bin Harith,
Omaiyah bin Khalaf, Zama‘a bin Al-Aswad, Tu‘aima bin ‘Adi, Abu Lahab, Ubai bin Khalaf, Nabih bin Al-
Hajjaj and his brother Munbih bin Al-Hajjaj. All were on the alert. As night advanced, they posted  assassins around the Prophet’s house. Thus they kept vigil all night long, waiting to kill him the  moment  he left his house early in the morning, peeping now and then through a hole in the door to make sure  that he was still lying in his bed. Abu Jahl, the great enemy of Islam, used to walk about haughtily and  arrogantly jeering at Muhammad’s words, saying to the people around him: “Muhammad claims that if  you follow him, he will appoint you rulers over the Arabs and non-Arabs and in the Hereafter your  reward will be Gardens similar to those in Jordan, otherwise, he will slaughter you and after death you  will be burnt in fire.” He was too confident of the success of his devilish plan. Allâh, the All-Mighty,  however, in Whose Hands lie the sovereignty of the heavens and earth, does what He desires; He  renders succour and can never be overpowered. He did exactly what He later said to His Prophet:
“And (remember) when the disbelievers plotted against you O Muhammad (Peace be upon him)  to imprison you, or to kill you, or to get you out (from your home, i.e. Makkah); they were  plotting and Allâh too was planning, and Allâh is the Best of the planners.” 8:30
At that critical time the plans of Quraish utterly failed despite the tight siege they laid to the Prophet’s  house, the Prophet (Peace be upon him) and ‘Ali were inside the house. The Prophet (Peace be upon  him) told ‘Ali to sleep in his bed and cover himself with his green mantle and assured him full security  under Allâh’s protection and told him that no harm would come to him. The Prophet (Peace be upon  him) then came out of the room and cast a handful of dust at the assassins and managed to work his  way through them reciting verses of the Noble Qur’ân:
“And We have put a barrier before them, and a barrier behind them, and We have covered them  up, so that they cannot see.” 36:9
He proceeded direct to the house of Abu Bakr who, immediately accompanied him and both set out  southwards, clambered up the lofty peak of Mountain Thawr, and decided to take refuge in a cave.
The assassins who laid siege to the house were waiting for the zero hour when someone came and  informed them that the Prophet (Peace be upon him) had already left. They rushed in and to their  utter  surprise, found that the person lying in the Prophet’s bed was ‘Ali not Muhammad (Peace be upon  him).
This created a stir in the whole town. The Prophet (Peace be upon him) had thus left his house on
Safar
27th, the fourteenth year of Prophethood, i.e. 12/13 September 622 A.D.
Knowing already that Quraish would mobilize all its potentials to find him, he played a clever trick on  them and instead of taking the road to Madinah in north side of Makkah as the polythiest would  expect,  he walked along a road least expected lying south of Makkah and leading to Yemen. He walked for 5  miles until he reached a rough rocky mountain called Thawr. There his shoes were worn out, some  said  he used to walk tiptoe in order not to leave a trail behind him. 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
