Bayhaqi 20900 — What renders the testimony of the people of innovation

Abu Abdullah al-Hafiz (may Allah have mercy on him) narrated from him (Abu Bakr al-Sibghi), regarding the proof that "the Qadariyyah are the Magians of this ummah": The Magians say that Allah Almighty created some things and not others: Allah Almighty created light, and Allah Almighty did not create darkness. The Qadariyyah say: Allah Almighty created some things and not others: Allah Almighty created the sound of thunder, but Allah Almighty did not create the sound of the flint. The Magians say that Allah Almighty did not create ignorance and forgetfulness. The Qadariyyah say that Allah Almighty did not create memory, knowledge and action. The Magians say that Allah Almighty does not lead anyone astray, and the Qadariyyah say the same, whereas Allah Almighty says: "He leads astray whom He wills." [Surah al-Ra'd: 27] And: "He intends to lead you astray." [Surah Hud: 34]
The Shaykh (may Allah have mercy on him) said: He (peace and blessings be upon him) called them Magians only because of these meanings, or some of them, and along with that he attributed them to the ummah.
