Sincerity

Once, the Prophet (peace be upon him) took an oath, invoking sincerity (nasiha) on the part of his Companions. What was meant by this was that mutual relationships should be free from insincerity. One should always work for the welfare of others and try to do good for them. One should not let any harm touch others. All of one's efforts should be directed towards helping others. One criteria of this is that one should prefer for others what one likes for oneself. The Prophet speaks of this as a prerequisite of faith. He observes: "By Him in whose hand is my life, one does not attain faith until one prefers for others what one chooses for oneself." (Bukhair, Muslim)
