Musnad Ahmad 582:3

Yahya ibn Sa'id narrated to us, from Ibn Abi Dhi'b, who said: 'Abdullah ibn al-Sa'ib ibn Yazid narrated to me, from his father, from his grandfather, from the Prophet, peace and blessings of Allah be upon him, who said: "Let not one of you take the property of his companion, neither in jest nor in earnest. And if one of you takes the staff of his brother, let him return it to him."
