Shabir Ally is a Canadian Muslim preacher who serves as the president of the Islamic Information & Dawah Centre International in Toronto, Ontario, Canada. Ally is known for promoting a contextual interpretation of the Quranic verses, but seeks to find their justification in similar expressions within the Christian Bible. He has debated William Lane Craig, David Wood, Nabeel Qureshi, Michael Licona and John Dominic Crossan. He has also debated apologists James White and Jay Smith.

The Christian doctrine of the Trinity (Latin: trinus "threefold") holds that God is one God, but three coeternal consubstantial persons or hypostases. These being the Father, the Son (Jesus Christ), and the Holy Spirit - as "one God in three Divine Persons". The three Persons are distinct, yet are one "substance, essence or nature" (homoousios).
