Abaya Ibn Rab’i asked Imam Ali (‘a) about the ability by which we can stand erect, sit, and do things. The Imam (‘a) answered, “You asked about the ability. Do you possess it with or without God?” Abaya could not find any answer. The Imam then said, “If you claim you possess it without God, I will kill you. And if you claim you possess it with God, I will kill you, too.” “What should I say, then?” asked Abaya. The Imam said: You possess it by the way of God who possesses it exclusively. If He gives you a part of it, then He is bestowing upon you, and if He seizes it from you, that will be a kind of His test. He is the possessor of the ability that He gives to you and He is the prevailing on the matters that you can do.
