People saw Rabia running through the streets of Basra one day with a torch in one hand and pitcher of water in the other. A woman pulled her aside and said, "Dearest Rabia, our teacher, what are you doing?" Rabia replied, "I want to put out the fires of Hell, and burn down the pleasures of Paradise. Because of them people only worship God out of fear of punishment or hope for reward when they could be worshipping God for love alone!
