Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said concerning the words of Allah, the Mighty and Majestic, 'And they planned that which they could not attain': "A man called al-Aswad intended to kill the Messenger of Allah (peace and blessings be upon him)."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ata bin al-Sa'ib (may Allah have mercy on him) except Sharik (may Allah have mercy on him), nor from Sharik (may Allah have mercy on him) except Janab (may Allah have mercy on him); Mubashshir (may Allah have mercy on him) is alone in narrating it."
