Muhammad Husayn Haykal The Treaty of Hudaybiyya prescribed...
Muhammad Husayn Haykal The Treaty of Hudaybiyya prescribed that any non Makkans wishing to join the camp of Muhammad or that of the Quraysh may do so without obstruction. On the basis of this provision, the tribe of Khuza'ah joined the ranks of Muhammad, and that of Banu Bakr joined the Quraysh. Between Khuzaah and Banu Bakr a number of old unsettled disputes had to be suspended on account of the new arrangement.
With the Quraysh now believing (after the battle of Mootah) that Muslim power had crumbled, Banu al Dil, a clan of Banu Bakr, thought that the occasion had come to avenge themselves against Khuzaah. (The Life of Muhammad, Cairo, 1935) Banu Bakr could not have attacked Khozaa without the connivance and encouragement if not the open support of the Quraysh.
Tabari, the historian, says that Ikrima bin Abu Jahl, Safwan bin Umayya and Suhayl bin Amr, all leading figures of Quraysh, disguised themselves and fought at the side of Banu Bakr against the Khozaa. Of these three, the last named was the chief signatory of the Quraysh to the Treaty of Hudaybiyya.
Maxime Rodinson In Rajab of the year 8 (November 629), in consequence of a vendetta which had been going for several decades, some of the more excited of the Qurayshites at their rear, attacked a group of the tribe of Khuza'a, Mohammed's allies, not far from Mecca. One man was killed and the rest badly mauled and forced to flee into the sacred territory of Mecca. Pursued even there they took refuge in two friendly houses. Shamefully the Banu Bakr laid siege to the houses.
In all twenty people of the Khuza'a were slain. (Mohammed, translated by Anne Carter) One of the chiefs of Khozaa, Amr bin Salim, went to Medina and appealed to the Prophet for his intervention. The Prophet was shocked to hear the story of the outrage. As an ally of the Khozaa, he had to defend them from their enemies. But before considering military action, he made an attempt to employ peaceful means to obtain redress and justice.
He sent a messenger to the Quraysh, and suggested that: *The clients of Quraysh, i.e., Banu Bakr, or Quraysh themselves pay blood-wit to the Banu Khozaa, or; *Quraysh should waive their protection of Banu Bakr, or; *They should declare the Treaty of Hudaybiyya to be void. Zarqani says that the man who answered for the Quraysh was Qurtaba bin Umar. He said to the envoy of the Prophet that only the last of the three terms was acceptable to them.
