Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said: "I did not participate in any pact of the Quraysh except the pact of 'Mutayyibeen', and I do not wish to break this pact even if I were to be given red camels in exchange for it." (The narrator states:) By 'Mutayyibeen' is meant Banu Hashim, Banu Umayyah, Banu Zuhrah, and Banu Makhzum. (Imam Ibn Hibban, may Allah have mercy on him, says:) In both narrations, it is mentioned that I participated in the pact of 'Mutayyibeen', whereas the Prophet Muhammad (peace and blessings be upon him) did not participate in the pact of 'Mutayyibeen' because the pact of 'Mutayyibeen' took place before the birth of the Prophet Muhammad (peace and blessings be upon him). The Prophet Muhammad (peace and blessings be upon him) participated in the pact of 'Hilf al-Fudul', and this too took place among the 'Mutayyibeen'. I have discussed this narration in detail in my book "Al-Tawreeh wal-Hajb".
