The Prophet (ﷺ) passed by a man of the Ansar when he was giving his brother a warning against modesty. The Apostle of Allah (ﷺ) said : Leave him alone, for modesty is a part of faith.
Sunan Abi Dawud Book 43, Hadith 23
← Previous Hadith 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.

Sunan Abi Dawud Book 43, Hadith 22 Next Hadith → We were sitting with `Imran b. Hussain and Bushair b. Ka`b was also there. `Imran b. Hussain reported the Messenger of Allah (ﷺ) as saying: Modesty is good altogether, or he said: Modesty is altogether good. Bushair b. Ka`b said : We find in some books that there is a modesty which produces peace and dignified bearing, and there is a modesty which produces weakness. `Imran b. Hussain repeated the same words. So `Imran became angry so much so that his eyes became red, and he said : Don’t you see that I am transmitting a tradition from the Messenger of Allah (ﷺ) and you are mentioning something from your books? He (Qatadah) said : We said : Abu Nujaid, it is sufficient.
