Quran (80:1-80:11)
The Prophet frowned and turned away
Because there came to him the blind man, [interrupting].
But what would make you perceive, [O Muhammad], that perhaps he might be purified
Or be reminded and the remembrance would benefit him?
As for he who thinks himself without need,
To him you give attention.
And not upon you [is any blame] if he will not be purified.
But as for he who came to you striving [for knowledge]
While he fears [ Allah ],
From him you are distracted.
No! Indeed, these verses are a reminder;

66:1
O Prophet, why do you prohibit [yourself from] what Allah has made lawful for you, seeking the approval of your wives? And Allah is Forgiving and Merciful.

Nabi S.A.W, in spite of the divine guidance, was a human being and could make mistakes but his mistakes were never intended and never grave and Allah S.W.T guided him to correct those mistakes through the revelations.
