It is narrated from Hazrat Zaid bin Aslam that Sayyiduna Umar bin Khattab, may Allah be pleased with him, asked the Messenger of Allah, peace and blessings be upon him, about kalalah. The Prophet, peace and blessings be upon him, said: "The verse that was revealed in the summer, at the end of Surah An-Nisa, is sufficient for you."
