Maliks Muwatta Book 047, Hadith Number 009.

Section : Modesty.

Yahya related to me from Malik from Salama ibn Safwan ibn Salama az-Zuraqi that Zayd ibn Talha ibn Rukana, who attributed it to the Prophet, may Allah bless him and grant him peace, said, "The Messenger of Allah, may Allah bless him and grant him peace, said, 'Every deen has an innate character. The character of Islam is modesty.'"
