Never to Be Questioned about Anything He Does
Imām Ibn Taimiyyah, may Allāh have mercy on him, said:
[E]very good thing from Him is a favor; every punishment, justice. He is [never] to be questioned about [anything] He does because of His perfect wisdom, mercy, and justice–not simply because of His insuperable force and might [or because of] His power and ability.
