What is the Hanafis' argument for the reprehensibility of relieving oneself while facing the sun or moon, given Ibn Al-Qayyim's statement that there is no Shar'i evidence for it?

According to the Hanbalis, it is disliked to face the sun or the moon while relieving oneself, and they justified this by saying that these two contain some of Allah's light.

This is the view of the majority of scholars, but the preponderant opinion is that there is no dislike, due to the absence of any authentic evidence prohibiting it.
