9. My father related: Sa`d ibn `Abd Allah said: Muhammad ibn `Isa, on the authority of Yunus ibn `Abd al-Rahman, on the authority of al-Hasan ibn Abu al-Siri, on the authority of Jabir ibn Yazid that I asked Abu Ja`far al-Baqir regarding Diving Unity. He replied: Verily, Allah – Blessed be the Names with which He is called upon and praised, and Exalted be the Essence of His Greatness – is One, United in Oneness in the Greatness of His Unity. Then He applied His Unity to His Creation. Therefore, He is One, Needless [Samad], the Most Holy [Quddus], everything serves Him, everything depends upon Him, and His Knowledge encompasses everything.
