Musnad Ahmad 790:142

'Affan narrated to us, Hammad narrated to us, Thabit informed us, that 'Imran ibn Husayn narrated that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Modesty is entirely good." Bashir ibn Ka'b said: "Indeed, there is weakness in it." 'Imran became angry and said: "I do not see myself narrating from the Messenger of Allah (peace and blessings of Allah be upon him) that he said: 'Modesty is entirely good,' and you say: 'Indeed, there is weakness in it!'" It was said that he shunned him and intended not to speak to him, then it was said to him: "He is as you like [i.e., he has retracted his statement or is repentant]."
