The most frequent expression in the Muslim world is inshallah, if God wills. It removes all guilt: blame it on Allah. If the oasis dries up and blows away, it was Allah's will. If you get caught sleeping with your brother's wife, it was Allah's will. Getting your hand or your cock or your head chopped off in reprisal is Allah's will, too. Nothing much gets done in the Budayeen without discussing how Allah is going to feel about it.
