“When a man is acting for our Lord’s pleasure, Allah is accepting it by himself and keeping it in His treasures. But our nafs (ego) likes to step into actions of worship for which Allah has promised Paradise in order to take rewards for itself. These actions are acceptable but only angels are writing them. To whoever is not asking for any reward, Allah gives him countless rewards. To do everything for the Lord’s pleasure makes our actions most high and precious, most lovely to Allah and lovely to everyone.”
