Based on this issue, the question of whether the slave owns or does not own is based. Whoever sees the partnership of causes without which causes cannot exist does not establish a partner in ownership, because the cause is from ownership, and it is like a machine, and the machine creates in it what is the property of the creator, just as the machine is the property of the creator and what it owns. The machine is a thing, so for this reason the takbīr is restricted from the partner in the kingdom, not in the creation, because God Almighty created things on a basis .
