9:14Fight them. God will punish them at your hands, and humiliate them, and help you against them, and heal the hearts of a believing people.

9:19Do you consider giving water to pilgrims and maintaining the Sacred Mosque the same as believing in God and the Last Day and striving in God’s path? They are not equal in God’s sight. God does not guide the unjust people.

9:37Postponement is an increase in disbelief—by which those who disbelieve are led astray. They allow it one year, and forbid it another year, in order to conform to the number made sacred by God, thus permitting what God has forbidden. The evil of their deeds seems good to them. God does not guide the disbelieving people.

9:71The believing men and believing women are friends of one another. They advocate virtue, forbid evil, perform the prayers, practice charity, and obey God and His Messenger. These—God will have mercy on them. God is Noble and Wise.
