the Declaration of Prophesy Mohammed, the successor of Hashim, declared his being the anticipated prophet whom had been favored by God for leading the Arabs and the mankind to the right path. He declared that the evidence of his prophesy had been God's words. A little group of eloquent individuals and those who were harshly treated in this world, followed Mohammed. F. the Hashimites' Guarding Mohammed With all their forces, the Hashemites embraced Mohammed.
The leaders of Quraish threatened that they would kill him. In fact, they spread a rumor of Mohammed's being killed. AbuTalib gathered the Hashemite men and gave each a hard bar. Walking with the sons of Hashim and his, AbuTalib raised his voice at the people of Quraish: “O people of Quraish! Do you realize what I am to do?” “No, we do not.” they answered. AbuTalib ordered his people to show what they were keeping in their hands. Each showed the hard bar he had.
AbuTalib commented: “By God I swear, if you kill him — Mohammed — I will never keep any of you alive unless we both are terminated.” Accordingly, people of Quraish were defeated. AbuJahal countered the largest share of that defeat.[7] G. Not for the Favor of the Pagans, It Was Envy, and Preserving the Political Form Led by AbuSufian, the other clans of Quraish exerted all their efforts for the sake of facing Mohammed.

[7] bnSa'd's AtTabaqat, part.1, page2023. Issuing a total boycott against the Hashemites. The Quraishi clans, including Teim and Edi, ostracized the Hashemites. They restricted them in the Cols of AbuTalib for three continuous years.
The Hashemites, during that period, had to have from the leaves of the trees due to the starvation they suffered. Their children, likewise, had to suck the sands due to their thirstiness. This is an indisputable fact that is as clear as sunlight. Neither Mohammed nor did the Hashemites submit to the Quraishi people. Finally, God refuted the trickeries of the Quraishi people and leaders. After a three year boycott, the blockade proved its failure.
As they realized that Mohammed would soon immigrate to Yathrib, where he could find supporters and could establish a base for his advocacy, the clans of Quraish decided unanimously to kill him.
