This negation is offered without the slightest proof, nor is there any proof to support it.

Instead, “they have denied what they cannot encompass in knowledge, and its interpretation has not yet come to them” (Qur’an 10:39). This point deserves careful notice, for the main pillar of their corrupt restriction is sheer, uninformed denial and rejection.
Furthermore, through direct observation, mass-transmitted reports, and conclusive proofs, we—together with many others—know with certainty that this restriction is false. In reality, countless events occur in this world that arise from living, rational beings other than human souls, other than elemental bodies, and other than the celestial spheres and their forces.
