How can God Almighty's grace be understood within the context of the interplay of people's actions and contributions, and can everything be attributed to God's grace despite the existence of people's grace, as in a mother buying food or the state providing aid, and based on the saying of the Prophet, peace and blessings be upon him, "Whoever does not thank people does not thank God"?

Attributing allفضل (grace/favor/merit) to Allah Almighty is a due and obligatory right, because He is the Creator, the Facilitator, and the Disposer. This does not contradict attributingفضل to whomever Allah has used as an instrument for it, but this attribution is of a lower rank than the first. Equating Allah with His creation in rank is a minor shirk (definition) (associating partners with Allah), such as saying: "Were it not for Allah and you." The correct statement is: "Were it not for Allah, then so-and-so," because the conjunction "wa" (and) implies equality, whereas "thumma" (then) implies sequence. Matters and the benefit of causes must primarily be attributed to Allah's will, then the cause is mentioned. The point is that attributingفضل to Allah Almighty is a reality, and attributing it to a creature is correct in terms of causality. Therefore, one must first thank Allah, then thank the one through whom Allah brought about good, as the Prophet (peace be upon him) said: "Whoever does not thank people, does not thank Allah," and "Whoever does you a kindness, reciprocate it."
