O Ye who believe ! approach not prayer while ye are intoxicated until ye know that which ye say , nor yet while ye are polluted , save when ye be way faring , until ye have washed your selves . And if ye be ailing or on a journey , or one of you cometh from the privy have touched women , or ye and ye find not water , then betake your selves to clean earth and wipe your faces and your hands therewith ; verily Allah is ever Pardoning , Forgiving .
