Imam Sadiq (a.s) said: “God the Almighty sent a Prophet to a nation and asked him to fight with them. The Prophet complained to God about being weak. God the Almighty said: “Either choose to fight, or go to hell with them.” That Prophet (a.s) said: “O' my Lord! I cannot withstand the Fire.” Then God revealed to him that he would become victorious during that same year. Then that Prophet told his followers that God had ordered them to go to war, and he has said they are weak. But God has said either to fight or go to Hell. He told his followers to choose between fighting and going to Hell. They said that they could not withstand the Fire. Then he told them that God had revealed to him that they would be victorious during that same year. They said they would do whatever he ordered them to do.” Then Imam Sadiq (a.s) said: “God appointed another Prophet and ordered him to go fight a nation. He complained of his weakness, and God the Almighty revealed to him that they would be victorious after fifteen years. When he told his followers about this, they said: “There is no strength nor power but in, or by means of, God the High, the Great.” He then told them that God has revealed to him that they will be victorious after fifteen years. They said: “Whatever God decides. There is no strength nor power but in, or by means of, God the High, the Great.” Since they entrusted their affairs to God, God made them victorious that same year.”
