Does using the elevator after swearing not to use it, out of fear of God's wrath, despite being compelled to do so, constitute an act that angers God?

Your ascent in the elevator again after the oath necessitates an expiation for breaking an oath (kaffarat yamin). This involves feeding ten poor people, or clothing them, or emancipating a slave. If you are unable to do so, then you must fast for three days. There is no blame upon you to use the elevator after the expiation, as the Prophet, peace and blessings be upon him, said: "Whoever takes an oath and then sees something better than it, let him do that which is better and make expiation for his oath."
