Muhammad ibn Abi Bakr al-Muqaddami and Muhammad ibn al-Muthanna narrated to us — and the wording is that of Ibn al-Muthanna — they said: Yahya ibn Sa'id narrated to us, Hisham narrated to us, Qatadah narrated to us, from Salim ibn Abi al-Ja'd, from Ma'dan ibn Abi Talhah, that 'Umar ibn al-Khattab delivered a sermon on a Friday, and he mentioned the Prophet of Allah, peace and blessings be upon him, and mentioned Abu Bakr. Then he said: "Indeed, I do not leave after me anything more concerning to me than the kalalah. I never asked the Messenger of Allah, peace and blessings be upon him, about anything as much as I asked him about the kalalah, and he never spoke harshly to me about anything as he spoke harshly to me about it — until he poked his finger into my chest and said: 'O 'Umar, does not the verse of summer, which is at the end of Surat al-Nisa', suffice you?' And if I live, I will rule on it with a ruling by which those who read the Qur'an and those who do not read the Qur'an may judge."
