Worry about your own sins
Imam Hussein (A.S) said: Do not be of those who worry about other people's sins but are relaxed about the consequences of their own because, the paradise cannot be taken from the Almighty with fraud and deceit. The human being will not attain any devine rewards or blessings except by obedience and devotion to Allah (SWT) .
