Musannaf Ibn Abi Shayba 18:1030

Abu Bakr narrated to us, he said: Abda bin Sulayman narrated to us, from Mujalid, from al-Sha’bi, from Ibn Abbas, that he looked at the Kaaba and said: "How great is your sanctity and how great is your right! But the Muslim is greater in sanctity than you. Allah has made sacred his wealth, his blood, his honor, harming him, and that one should think evil of him."
