Musannaf Ibn Abi Shayba 17:1307

Al-Fadl ibn Dukayn narrated to us, from Musa ibn Ali, from his father, from Abd al-Aziz ibn Marwan, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The worst thing in a man is stinginess that makes him anxious, and cowardice that strips him of his heart."
