An-Nisa 4:43

Ya ayyuha allatheena amanoola taqraboo assalata waantum sukarahatta taAAlamoo ma taqooloona walajunuban illa AAabiree sabeelin hattataghtasiloo wa-in kuntum marda aw AAala safarin awjaa ahadun minkum mina algha-iti aw lamastumuannisaa falam tajidoo maan fatayammamoo saAAeedantayyiban famsahoo biwujoohikum waaydeekuminna Allaha kana AAafuwwan ghafoora

O you who have believed, do not approach prayer while you are intoxicated until you know what you are saying or in a state of janābah, 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 Pardoning and Forgiving.

O you who believe! Do not go near Salāh when you are intoxicated, until you know what you say, nor in a state of ‘major impurity’.,-save when you are traversing a way-until you take a bath. If you are sick, or in travel, or if one of you has come after relieving himself, or you have had contact with women, and you find no water, go for some clean dust and wipe your faces and hands (with it). Surely, Allah is Most-Pardoning, Most-Forgiving.
