Prohibition of raising one's Eyes towards the sky during As-Salat (The Prayer)

'Aishah (May Allah be pleased with her) said:
I asked the Messenger of Allah ﷺ about random looks in Salat (prayer), and he replied, "It is something which Satan snatches from the slave's Salat."

[Al-Bukhari].

عن عائشة رضي الله عنها قالت: سألت رسول الله ﷺ عن الالتفات في الصلاة فقال: "هو اختلاس يختلسه الشيطان من صلاة العبد" ((رواه البخاري)).
