Al-Bukhari narrated it in his Sahih from Umar ibn al-Khattab.
A man was called "Himar" (Donkey).
And he used to make the Prophet laugh.
And he used to drink alcohol, and the Prophet would lash him.
Then he was brought to him once.
So a man said, 'May Allah curse him; how often he is brought to the Prophet!'
The Prophet said, 'Do not curse him, for he loves Allah and His Messenger.'
This shows that a sinner through drinking and otherwise can still love Allah and His Messenger.
And the love of Allah and His Messenger is the strongest bond of faith.
Just as a devout worshipper may, because of the innovation and hypocrisy in his heart, be disliked by Allah and His Messenger.
In this regard, as has been widely narrated in the Sahih collections and others.
From the hadith of Ali ibn Abi Talib and Abu Sa'id al-Khudri about the Prophet.
He mentioned the Khawarij and said,
One of you would consider his prayer insignificant compared to their prayers.
And his fasting compared to their fasting.
And his recitation compared to their recitation; they recite the Quran, but it does not go beyond their throats.
They exit from Islam as an arrow passes through its target.
Wherever you encounter them, then kill them.
For indeed in killing them is a reward with Allah for whoever kills them.
If I were to encounter them, I would surely kill them like the killing of Aad.
And these are the companions of the Messenger of Allah, with the Commander of the Faithful, Ali ibn Abi Talib, by the command of the Prophet.
And the Prophet said about them in the authentic hadith,
A group will defect from the best faction of the Muslims, and the closer of the two parties will kill them.
And this is why the leaders of the Muslims, like Sufyan al-Thawri, said that innovation is more beloved to Iblis than sin.
