Conspiracy of murdering the Holy Prophet
After the settlement in Yathrib of Meccan Muslims, the chiefs of Quraysh realized that Yathrib had turned into a strong shelter for the Holy Prophet and his followers, and that people of Yathrib were ready to fight for their faith. For this reason, they feared the Holy Prophet's emigration. This matter caused the Quraysh to face several problems:
(1) Muslims were no longer under their domination and control, because Yathrib was an independent city and Quraysh had no power there.
(2) Since people of Yathrib had convened a war treaty with the Holy Prophet, he might then start a siege on Mecca for revenge.[1]
(3) Even without a probable war, Quraysh were still at a loss, because Yathrib was a lucrative market for their merchants and they would face economic disasters through losing control over this city.
(4) Yathrib was on the trade route from Mecca to Damascus and Muslims could easily make this route unsafe and vulnerable; they might also jeopardize trade as a whole.
These worries forced the chiefs of Quraysh to gather at D¡r al-Nidwah (the consular center) for further consultation and deliberations. Some proposed that the Holy Prophet be exiled or imprisoned. However, these two proposals were rejected for certain reasons. Finally, they decided to murder him although such an act would not look very simple, because Ban£-H¡shim would seek revenge. To avoid such expected vengeance, they decided to appoint one young man from every tribe so that they could murder him in his bed. In this way, Ban£-H¡shim could not rise to avenge because the assassination would have taken place with several men from different tribes; and Ban£-H¡shim could not fight all these tribes; so, they would have to receive ransom and blood-money and the story would come to an end. To carry out their plot, chiefs of Quraysh selected the first night of Rab¢` al-Awwal. God refers to their conspiracy with the following words:
And when those who disbelieved devised plans against you that they might confine you, slay you, or drive you away; and they devised plans and Allah too had arranged a plan; and Allah is the best of planners. (8:30)
The Prophet's Migration
Through Divine revelation, the Holy Prophet knew about the conspiracy of D¡r al-Nidwah; he was then ordered by God to leave Mecca. He informed Imam `Al¢ (a.s) about his plan and ordered him to replace him in bed that night and cover himself with his bedspread. Imam `Al¢ (a.s) immediately accepted this mission.
Accompanied by Ab£- Bakr, the Holy Prophet headed for Thawr Cave to the south of Mecca that night and stayed there for three days until chiefs of Quraysh despaired of finding him. He wanted to find a safe time to continue his migration. God, in the Holy Qur'¡n, refers to the Holy Prophet's loneliness and to the worries of his companion. Despite all precautious actions that the chiefs of Quraysh had taken, they could not locate the Holy Prophet:
If you will not aid him, Allah certainly being the second of the two, when they were both in the cave, when he said to his companion: Grieve not, surely Allah is with us, So Allah sent down His tranquility upon him and strengthened him with hosts which you did not see, and made lowest the word of those who disbelieved; and the word of Allah that is the highest; and Allah is Mighty, Wise. (9:40)
