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

Believers! Do not draw near to the Prayer while you are intoxicated¹ until you know what you are saying² nor while you are defiled³ - save when you are travelling - until you have washed yourselves.⁴ If you are either ill or travelling or have satisfied a want of nature or have had contact with women⁵ and can find no water, then betake yourselves to pure earth, passing with it lightly over your face and your hands.⁶Surely Allah is All-Relenting, All-Forgiving.
