The Holy Prophet’s (Sallallahu alaihi wa sallam) sight was such that when He (Sallallahu alaihi wa sallam) saw Allah SWT, neither did His eye did not blink nor cross the limits of propriety (adab).”
(His) sight never swerved nor did it go wrong! Surah Najm (53:17)
The Holy Prophet (Sallallahu alaihi wa sallam) would see in all 6 directions at once-i.e. front, back, right left, above and below.
Nothing in the earth or sky is hidden from His sight. (Sallallahu alaihi wa sallam).
Hadith from Sahih Bukhari
It has been narrated on the authority of Hadhrat Abu Hurairah who reports that the Holy Prophet (Sallallahu alaihi wa sallam) said: “Do you think that only the spot of prostration is before Me? By Allah, your ruku and your sincerity are not hidden from Me. Certainly I see you even from behind My back.”
