Why were the eyes of those who raise their gaze to the sky during prayer not snatched away, despite the severe warning mentioned in the Hadith: "They must desist from that, or their eyesight will be snatched away"?

Many of those who raise their eyes to the sky during prayer are unaware of the prohibition and warning mentioned in the Hadith (definition): "Let them desist from that, or their eyesight will be snatched away." The non-occurrence of the threat does not mean it will not happen. It might not occur due to forgiveness, pardon, or the doer's ignorance of the ruling. Some scholars have suggested that the warning is figurative, but the original understanding is that it is literal, and its non-occurrence falls under the category of a suspended threat.
