The clan of Banu Hashim was monolithic in its support of Muhammad, and the leaders of the Quraysh found themselves powerless before it. After long deliberation and debate, the Quraysh agreed that the “intractability” of Banu Hashim called for sterner measures, and they decided to isolate and ostracize not only Muhammad but all his protectors as well, viz., the clan of Banu Hashim. It was inevitable that any attempt to ostracize Banu Hashim would lead to a polarization of the groupings in Makkah.
Everyone in Makkah would have to declare himself for or against Banu Hashim. But it soon became obvious that in this confrontation, Banu Hashim would find the whole of Arabia ranged against itself. Muhammad Husayn Haykal It is nearly impossible for us to imagine the intensity and extent of the efforts which Quraysh spent in its struggle against Muhammad, or its perseverance during many long years of that struggle.The Quraysh threatened Muhammad and his relatives, especially his uncles.
It ridiculed him and his message, and it insulted him as well as his followers. It commissioned its poets to revile him with their sharpest wits and to direct their most caustic sting against his preaching. It inflicted injury and harm on his person and on the persons of his followers. It offered him bribes of money, of royalty and power, of all that which satisfies the most fastidious among men.
It not only Banushed and dispersed his followers from their own country but injured them in their trade and commerce while impoverishing them. It warned him and his followers that war with all its tragedies would befall upon them. As a last resort, it began a boycott of them designed to starve them.
(The Life of Muhammad, Cairo, 1935) A few days before the beginning of the year 7, the leaders of the various clans of Quraysh met in a solemn conclave in the “town hall” of Makkah, and there, by consensus, they drafted and signed a document which stipulated that unless the clan of Banu Hashim surrendered Muhammad to them, it would be subjected to an economic and social boycott.
They pledged themselves not to buy anything from, nor to sell anything to, the members of the Banu Hashim, and they placed intermarriage with them under proscription. This covenant was sent to the other tribes for ratification. When they had ratified it, it was solemnly suspended on the wall of the Kaaba. The ratification of the covenant was a belligerent act!
