While we were in the company of the Prophet, he said, "While I was asleep, I saw myself in Paradise
and there I beheld a woman making ablution beside a palace, I asked, To whom does this palace
belong? 'They said, To `Umar bin Al-Khattab.' Then I remembered `Umar's Ghaira (concerning
women), and so I quickly went away from that palace." (When `Umar heard this from the Prophet), he
wept and said, "Do you think it is likely that I feel Ghaira because of you, O Allah's Messenger (ﷺ)?"
Sahih al-Bukhari Book 59, Hadith 53
The Messenger of Allah (ﷺ) entered the mosque and saw a man who had finished his prayer, and was reciting the tashahhud saying: O Allah, I ask you, O Allah, the One, the eternally besought of all, He begetteth not, nor was He begotten, and there is none comparable unto Him, that you may forgive me my sins, you are Most Forgiving, Merciful.
He (the Prophet) said: He was forgiven (repeating three times.)
Sunan Abi Dawud Book 2, Hadith 596
