يَا أَيُّهَا الَّذِينَ آمَنُواْ لاَ تَقْرَبُواْ الصَّلاَةَ وَأَنتُمْ سُكَارَى حَتَّىَ تَعْلَمُواْ مَا تَقُولُونَ وَلاَ جُنُبًا إِلاَّ عَابِرِي سَبِيلٍ حَتَّىَ تَغْتَسِلُواْ وَإِن كُنتُم مَّرْضَى أَوْ عَلَى سَفَرٍ أَوْ جَاء أَحَدٌ مِّنكُم مِّن الْغَآئِطِ أَوْ لاَمَسْتُمُ النِّسَاء فَلَمْ تَجِدُواْ مَاء فَتَيَمَّمُواْ صَعِيدًا طَيِّبًا فَامْسَحُواْ بِوُجُوهِكُمْ وَأَيْدِيكُمْ إِنَّ اللّهَ كَانَ عَفُوًّا غَفُورًا
﴿٤٣﴾
سورة النساء
(4/43) O you who believe (who are âmenû)! Do not approach the Prayer when you are intoxicated until you know what you say, nor when you are under an obligation to perform a total ablution (when you are in state of impurity following sexual relations and before bathing) unless travelling, until you perform a total ablution. And if you are ill, or on a journey or one of you comes from the privy or you have touched the women, and you can not find water, perform Tayammum with clean earth and rub your faces and your hands with it. Surely, Allah is Oft-Pardoning, Oft-Forgiving.
Surah An-Nisa
