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. Allah intendeth not to lay upon you a hardship, but intendeth to purify you and to complete His favour upon you, that haply ye may return thanks.
