Musnad Ahmad 790:100

Yazid narrated to us, Khalid bin Rabah Abu al-Fadl informed us, Abu al-Siwar al-Adawi narrated to us, Imran bin Husayn narrated to us, from the Prophet, may Allah bless him and grant him peace, who said: "Modesty is entirely good." A man from the tribe said: "It is said in wisdom: Indeed, part of it is reverence for Allah, and part of it is weakness." Imran said to him: "I narrate to you from the Messenger of Allah, may Allah bless him and grant him peace, and you narrate to me from scrolls?"
