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 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.
