Sulaiman bin Harb سليمان بن حرب · General Behavior (Kitab Al-Adab)

I never said that when any man brought his mouth to the ear of the Messenger of Allah (ﷺ) and he withdrew his head until the man himself withdrew his head, and I never saw that when any man took him by his hand and he withdrew his hand, until the man himself withdrew his hand.

A woman came to the Messenger of Allah (ﷺ) and said: Messenger of Allah! I have given birth to a boy, and call him Muhammad and AbulQasim as kunyah (surname), but I have been told that you disapproved of that. He replied: What is it which has made my name lawful and my kunyah unlawful, or what is it which has made my kunyah unlawful and my name lawful?

The Prophet (ﷺ) said: When a man makes a promise to his brother with the intention of fulfilling it and does not do so, and does not come at the appointed time, he is guilty of no sin.
