Wada'ah al-Hamdi (may Allah have mercy on him) related that he was at the side of Sayyiduna Malik bin Abdullah al-Ghafiqi (may Allah be pleased with him) while Sayyiduna Uqbah bin Amir (may Allah be pleased with him) was relating narratives, and Malik (may Allah be pleased with him) said: This companion of yours is heedless and mortal. The Messenger of Allah (peace and blessings be upon him) gave us this instruction at the Farewell Pilgrimage: "Hold fast to the Qur'an, for you will soon return to people who long to hear hadith from me. So whoever has understood something, let him narrate it; and whoever fabricates lies about me, let him take his seat - or he said: a portion - in Hell." The narrator said: I do not remember which of the two he said.
