O you who believe! do not go near Prayer when you are not in full possession of your senses, until you understand all that you say (in your Prayers); nor (occupy yourselves in Prayer) when you are unclean (and under an obligation to have a bath) until you have bathed yourselves. But (you can do without a bath) when you are travelling a long way. If you are taken ill or (are) on a journey, or if one of you comes from the privy, or you have had (sexual) contact with women and you find no water (for bathing or ablution) then have recourse to pure and clean dust and wipe your faces and your hands (therewith). Indeed, Allâh is Most Benign, Great Protector.
