Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Among the major sins, the first is associating partners with Allah; (and the other major sins are:) killing a soul unjustly, consuming usury (riba), consuming the wealth of an orphan, fleeing from the battlefield, accusing chaste women, and returning to the desert life of the Bedouins after having emigrated."
Al-Bazzar recorded it; its chain contains a narrator, Umar bin Abi Salamah, whom Shu'bah and others declared da'if (weak), while Abu Hatim, Ibn Hibban and others declared him thiqah (trustworthy).
