Why is attributing Isa or the angels to Allah considered shirk? I know it’s a lie and that it assigns deficiencies to Allah, but I don’t understand why it’s shirk — a father is not necessarily the same as his child. Sorry for this question, but I need an answer. Jazākallāhu khayran

Ustadh AbdulAziz al-Haqqan
Because they added an entity to Allah literally from Him subhanahu wataala, u understand? We seek refuge by Allah.
