Al-Matalib al-'Aliyah 3592 — Surah al-Ma'idah

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) recited Surah al-Ma'idah and Surah al-Tawbah in his sermon, then the Prophet (peace and blessings be upon him) said: "Whatever Allah Almighty has made lawful in these two surahs, regard it as lawful, and whatever Allah has made unlawful in them, regard it as unlawful."
In the chain of this hadith, the narrator Ibrahim bin al-Hakam bin Aban is da'if (weak); Imam Ibn Abi Shaybah recorded it in al-Musannaf (31802) and Imam al-Bayhaqi in al-Sunan al-Kubra (15093).
