Answered by Shaykh Faraz Rabbani
Is it shirk to say that something is impossible and then do it, as it means that you can do the impossible?
Sorry if the question sounds ignorant.
In the Name of Allah, the Merciful and Compassionate
I hope you’re doing well, insha’Allah.
First, may Allah Most High bless you for asking. No sincere question is ignorant. The Prophet (peace and blessings be upon him) encouraged his Companions to ask questions, and said, “The only cure for confusion is asking.” [Abu Dawud and Ahmad; sound]
Human speech is assumed to be conditioned by the norms of created things. Thus, when we say something is “impossible” or “nothing is impossible,” we mean that it is “normally not possible” and “nothing in itself possible is in itself impossible.”
Also, Allah and the Messenger (peace and blessings be upon him) teach us that the basis of human actions is assumed to be soundness. This includes human speech. [Karkhi, Usul; others]
Thus, what you mentioned is neither shirk — which is to associate partners with Allah in His worship, or in ascribing Divinity to other than Allah — nor is it sinful.
And Allah is the giver of success and facilitation.
