Meccans break the Treaty of Hudaibiyah

In relation to this we also find that when Banu Bakr, who were allies of the Quraish, violated the Treaty of Hudaibiyyah and attacked Banu Khuza‘ah, who were allies of the Muslims, the Quraish also provided Banu Bakr with weapons and mounts and disregarded the conditions of the Treaty of Hudaibiyyah. At that time, Abu Sufyan entered Medina in order to renegotiate the Treaty of Hudaibiyyah.

He approached the Holy Prophet (sa), but the Holy Prophet (sa) did not reply to anything he said. He then approached Hazrat Abu Bakr (ra) and asked him to speak to the Holy Prophet (sa). However, he too said that he would not do so. Abu Sufyan then approached Hazrat Umar (ra) and spoke to him. In reply, Hazrat Umar (ra) said, “Do you want me to present your case to the Holy Prophet (sa)? By God! Even if I merely had a straw, I would use it to fight against you!”
