Beware of injustice, for oppression will be darkness on the Day of Resurrection; and beware of stinginess because it doomed those who were before you. It incited them to shed blood and treat the unlawful as lawful.
MuhammadIf men had been forbidden to make porridge of camel's dung, they would have done it, saying that they would not have been forbidden to do it unless there had been some good in it.
Muhammad
