Is the saying: "O Sky, pour your wrath upon the foolish" considered a supplication to other than Allah?

If the call to the sky is real, intended to ask it to pour wrath upon the foolish, then this is major shirk (polytheism) and worship of other than Allah, because none but Allah can do that. However, if the call is metaphorical and not intended as a real supplication, then there is fundamentally no objection to it. Nevertheless, it is prohibited if it contains objectionable phrases that might suggest a belief that nature acts in the universe.

The esteemed scholar Al-Sahsawani explained that prohibiting the calling upon the dead, inanimate objects, and the absent is subject to two conditions: 1. That the call be real and not metaphorical. 2. That something is requested from the one called upon that none but Allah can do, such as bringing benefit or removing harm. This is disbelief and shirk.

However, if the intention of the call is for the dead, inanimate object, or absent one to supplicate for the caller in the presence of the Lord, then calling upon the dead far from the grave or calling upon the absent implies believing that they possess knowledge of the unseen, which is shirk and disbelief. Calling upon inanimate objects and the dead with this intention is, at the very least, an innovation and folly. As for a real call that is not intended to bring benefit or harm, it is madness and foolishness, while no one prohibits a metaphorical call.

Indeed, one is declared a disbeliever only by a real call in which something is requested from the dead and inanimate objects that none but Allah can do.
