Mujahid (may Allah have mercy on him) narrates: Sayyidah Juwayriyah (may Allah be pleased with her) said to the Prophet (peace and blessings be upon him): Your (peace and blessings be upon him) wives boast over me and say that the Messenger of Allah (peace and blessings be upon him) did not marry you. So he (peace and blessings be upon him) said: "Did I not make your dowry great? Did I not free forty people of your tribe?"
