O ye who believe ! when ye stand up for the prayer wash your faces and your hands unto the elbows , and wipe your heads , and wash your feet unto the ankles . And if ye be polluted , then purify yourselves And if ye be ailing or on a journey or one of you cometh from the privy or ye have touched women , and ye find not water , then betake yourselves to clean earth and wipe your faces and hands therewith .
