Why is it according to the hadith, that we should not look up during Salaah?
Why only up and not any other direction?
In Salaah we are required to have khushoo' or concentration; this cancels out by looking in any direction. Looking up is more serious because of the texts which warn of severe punishment for doing so. The Prophet (ﷺ) said, “ Let those who raise their gaze up during prayer stop doing so, or else their sights would not return to them. [i.e. lose their eyesight]
