Sayyiduna Umar (may Allah be pleased with him) narrates that I asked the Prophet (peace and blessings of Allah be upon him) about kalalah, so the Prophet (peace and blessings of Allah be upon him) said: "The verse about kalalah that was revealed in the summer is sufficient for you." Asking the Prophet (peace and blessings of Allah be upon him) about this issue was more beloved to me than acquiring red camels.
