«Strive in the way of God with a service worthy of Him. He has chosen you and laid no hardship on you in the way of faith, the faith of your forbear Abraham. He named you Muslim earlier, and in this (Qur'an), in order that the Prophet be witness over you, and you be witness over mankind. So be firm in devotion, pay the zakat, and hold on firmly to God. He is your friend: How excellent a friend is He, how excellent a helper!»
