“We find in (Imam) Ali ibn Abitalib's (a.s) book that God's Prophet (a.s) used to say the following when he gave a sermon on the mosque pulpit: “I swear by God who has no partners that no good of this world or the Hereafter has been granted to any believer, except due to his good opinion about God, his good behavior, and his avoidance of gossiping and slandering. And I swear by God who has no partners that God will not punish anyone after repentance and seeking forgiveness except due to his bad opinion about God, insufficient hope in God, bad behavior, and gossiping about believers. I swear by God who has no partners that there are no believers who have a good opinion about God and receive anything less than they expect from Him. This is so since God is Benevolent and has authority over all that is good, and is ashamed of one of his servants having a good opinion about Him and He acting otherwise. Therefore have a good opinion about God and be inclined to Him.”
