“Abu ‘Abd Allah (a.s.), has said that Amir al-Mu’minin (a.s.), would not launch attacks against the enemy until after the declining of the sun toward the west. He would say, ‘At such time the doors of heaven open up, mercy comes forward and victory descends.’ He would also say, ‘Such time is closer to the night, prone to reduced killing, pursuers return and fleeing ones disappear.’”
