"Say (O Muhammad sal-Allaahu 'alayhe wa sallam): "Shall we invoke others besides Allaah (false deities), that can do us neither good nor harm, and shall we turn on our heels after Allaah has guided us (to true Monotheism)? - like one whom the Shayaateen (devils) have made to go astray, confused (wandering) through the earth, his companions calling him to guidance (saying): 'Come to us.' " Say: "Verily, Allaah's Guidance is the only guidance, and we have been commanded to submit (ourselves) to the Lord of the 'Alameen (mankind, jinns and all that exists);" [Al-An'aam (6):71]

Narrated Abu Musa:

The Prophet was asked about things which he did not like, but when the questioners insisted, the Prophet got angry. He then said to the people, "Ask me anything you like." A man asked, "Who is my father?" The Prophet replied, "Your father is Hudhafa." Then another man got up and said, "Who is my father, O Allah's Apostle ?" He replied, "Your father is Salim, Maula (the freed slave) of Shaiba." So when 'Umar saw that (the anger) on the face of the Prophet he said, "O Allah's Apostle! We repent to Allah (Our offending you)." [The Book of Knowledge Volume 1, Book 3, Hadeeth 92]
