An-Nisa 4:43 يا ايها الذين امنوا لا تقربوا الصلاة وانتم سكارى حتى تعلموا ما تقولون ولا جنبا الا عابري سبيل حتى تغتسلوا وان كنتم مرضى او على سفر او جاء احد منكم من الغايط او لامستم النساء فلم تجدوا ماء فتيمموا صعيدا طيبا فامسحوا بوجوهكم وايديكم ان الله كان عفوا غفورا ٤٣

O ye who believe! Draw not near unto prayer when ye are drunken, till ye know that which ye utter, nor when ye are polluted, save when journeying upon the road, till ye have bathed. And if ye be ill, or on a journey, or one of you cometh from the closet, or ye have touched women, and ye find not water, then go to high clean soil and rub your faces and your hands (therewith). Lo! Allah is Benign, Forgiving.

O you who have believed, do not approach prayer while you are intoxicated until you know what you are saying¹ or in a state of janābah,² except those passing through [a place of prayer], until you have washed [your whole body]. And if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women [i.e., had sexual intercourse] and find no water, then seek clean earth and wipe over your faces and your hands [with it]. Indeed, Allāh is ever Pardoning³ and Forgiving.

O ye who believe! Approach not prayers with a mind befogged, until ye can understand all that ye say,- nor in a state of ceremonial impurity (Except when travelling on the road), until after washing your whole body. If ye are ill, or on a journey, or one of you cometh from offices of nature, or ye have been in contact with women, and ye find no water, then take for yourselves clean sand or earth, and rub therewith your faces and hands. For Allah doth blot out sins and forgive again and again.
