Imam Sadiq (a.s) said: “When Moses and Aaron (a.s) went to Pharoah, there were no illegitimately born companions with Pharoah. If there were any, they would have ordered Moses and Aaron to be killed. But those who were present said: “Save Moses and Aaron and this forced Pharaoh to think about them.” Then Imam Sadiq (a.s) placed his hand over his chest and said: “We are the same way. No one will rush to kill us unless he is born illegitimately.”
