Muhammad Quotes
A man asked Muhammad what was the mark whereby he might know the reality of his faith. Muhammad said, 'If thou derive pleasure from the good which thou hast performed and thou be grieved for the evil which thou hast committed, thou art a true believer.' The man said. 'In what doth a fault really consist' Muhammad said, 'when action pricketh thy conscience, forsake it.'
ibn Hanbal, Ahmad. Musnad Imam Ahmad bin Hanbal. Darussalam, 2012.
Muhammad was an Arab religious, social, and political leader and the founder of Islam. According to Islamic doctrine, he was a prophet, sent to preach and confirm the monotheistic teachings of Adam, Abraham, Moses, Jesus, and other prophets. He is believed to be the final prophet of God in all the main branches of Islam, though some modern denominations diverge from this belief. Muhammad united Arabia into a single Muslim polity, with the Quran as well as his teachings and practices forming the basis of Islamic religious belief.
