The sight (of the Messenger) did not swerve (so that he looked elsewhere and saw something different), nor did it go wrong (so that he might have seen an illusion)
(When he saw the Divine Manifestation) his eye deviated not (from the certainty of the Truth) nor did it wander away (from the invincible faith on which he stood)
His sight neither wavered (to the concept of an ‘other’) nor did it transgress its limit (the observation of the reality did not lead him to become Pharaoh-like and deify himself)!
Al-muntakhab fi tafsir al-Qur'an al-Karim
He -Muhammad- never turned aside, nor did he lose sight of anything he was meant to see at that site, nor did his mind's eyes wander here or there
