Sayyiduna Abu Shurayh Khuza’i Ka’bi (may Allah be pleased with him), who was among the companions of the Messenger of Allah (peace and blessings be upon him), narrates that on the day of the conquest of Makkah, the Messenger of Allah (peace and blessings be upon him) granted us special permission to fight against Banu Bakr, while he (peace and blessings be upon him) was still in Makkah. So, we killed their people and took our revenge well. After that, the Messenger of Allah (peace and blessings be upon him) forbade us from raising swords, meaning he ordered a complete cessation of fighting. However, the next day, some people from our tribe found a man from Banu Hudhayl within the boundaries of the Haram. He was coming to the Messenger of Allah (peace and blessings be upon him) with the intention of accepting Islam. Previously, during the time of ignorance, he had committed a crime with those people. They were searching for him, so they killed him, and they acted hastily lest he reach the Messenger of Allah (peace and blessings be upon him) and the Messenger of Allah (peace and blessings be upon him) forbid them from killing him. When this news reached the Messenger of Allah (peace and blessings be upon him), he became extremely angry. By Allah! I have never seen him more angry than that. We went to Sayyiduna Abu Bakr (may Allah be pleased with him) and Sayyiduna Ali (may Allah be pleased with him) and sought their intercession. We feared that due to our negligence and the displeasure of the Messenger of Allah (peace and blessings be upon him), we might be destroyed. When the Messenger of Allah (peace and blessings be upon him) performed the prayer, he stood up and praised and glorified Allah as He deserves, and then said: Allah Almighty has made Makkah a sanctuary; people did not make it a sanctuary. Allah Almighty granted me permission to fight in this sanctuary for a short period yesterday. Now, from today, it is again a sanctuary, and fighting here is forbidden, just as Allah Almighty had previously declared it forbidden. And three types of people are the most rebellious and defiant to Allah Almighty: one who kills someone within the boundaries of the Haram, the second who kills anyone other than his own killer, and the third who takes revenge for a crime committed before Islam. By Allah! I will surely pay the blood money (diyah) for the man you have killed. Then the Messenger of Allah (peace and blessings be upon him) paid his blood money.
