صلح الحديبية
In 629 the Dil clan of the Bakr tribe took revenge against the Khuza'a. Safwan and his slaves lent them weapons and assisted the attack. As the Bakr were allied to the Quraysh and the Khuza'a to the Muslims in Medina, this was a breach of the Treaty of Hudaybiyyah, and it triggered the Conquest of Mecca.
