Amir al-Mu'minin (peace be upon him): Imam Husayn (peace be upon him) said: A Jew from the people of Sham said to Imam Ali (peace be upon him): "Allah sent Musa (peace be upon him) to Fir'awn and showed him the greatest sign." Amir al-Mu'minin (peace be upon him) said: "It is likewise so — He sent Muhammad (peace be upon him and his family) to several pharaohs such as Abu Jahl, Utba ibn Rabi'a, Shayba, Abu al-Bakhtari, Nadr ibn al-Harith, Ubay ibn Khalaf, Munabbih and Nubayh the two sons of al-Hajjaj, and to the five mockers: Walid ibn al-Mughira al-Makhzumi, al-'As ibn Wa'il al-Sahmi, al-Aswad ibn Abd Yaghuth al-Zuhri, al-Aswad ibn al-Muttalib, and al-Harith ibn al-Talatila. He showed them miracles in the horizons and in themselves until the truth became clear to them."
