It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Muslims are bound by their (agreed) conditions, and making peace (settlement) between Muslims is permissible." Its narrators are from Madinah, and the two Shaykhs (Bukhari and Muslim) did not record it. It is one of the foundational principles of fiqh, and supporting narrations (shawahid) for it are also reported from Sayyidah Aishah and Sayyiduna Anas (may Allah be pleased with them both).

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Muslims are bound by their (agreed) conditions, as long as they are in accordance with the truth."

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Muslims abide by their conditions, as long as those conditions are in accordance with the truth."
