Sure: AN-NISĀ’ 

Vers : 43

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَقۡرَبُواْ ٱلصَّلَوٰةَ وَأَنتُمۡ سُكَٰرَىٰ حَتَّىٰ تَعۡلَمُواْ مَا تَقُولُونَ وَلَا جُنُبًا إِلَّا عَابِرِي سَبِيلٍ حَتَّىٰ تَغۡتَسِلُواْۚ وَإِن كُنتُم مَّرۡضَىٰٓ أَوۡ عَلَىٰ سَفَرٍ أَوۡ جَآءَ أَحَدٞ مِّنكُم مِّنَ ٱلۡغَآئِطِ أَوۡ لَٰمَسۡتُمُ ٱلنِّسَآءَ فَلَمۡ تَجِدُواْ مَآءٗ فَتَيَمَّمُواْ صَعِيدٗا طَيِّبٗا فَٱمۡسَحُواْ بِوُجُوهِكُمۡ وَأَيۡدِيكُمۡۗ إِنَّ ٱللَّهَ كَانَ عَفُوًّا غَفُورًا

O you who have believed, do not approach prayer while you are intoxicated until you know what you are saying[1] or in a state of janŒbah,[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, AllŒh is ever Pardoning[3] and Forgiving.


1- The use of intoxicants was later prohibited completely. See 5:90-91.
2- Literally, "distance." The state of one under obligation to perform ghusl (a complete bath) due to having had sexual intercourse or ejaculation.
3- Literally, able to erase and remove sins completely, leaving no trace of them in the record of deeds.


Sure: AL‑MĀ’IDAH 

Vers : 6

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِذَا قُمۡتُمۡ إِلَى ٱلصَّلَوٰةِ فَٱغۡسِلُواْ وُجُوهَكُمۡ وَأَيۡدِيَكُمۡ إِلَى ٱلۡمَرَافِقِ وَٱمۡسَحُواْ بِرُءُوسِكُمۡ وَأَرۡجُلَكُمۡ إِلَى ٱلۡكَعۡبَيۡنِۚ وَإِن كُنتُمۡ جُنُبٗا فَٱطَّهَّرُواْۚ وَإِن كُنتُم مَّرۡضَىٰٓ أَوۡ عَلَىٰ سَفَرٍ أَوۡ جَآءَ أَحَدٞ مِّنكُم مِّنَ ٱلۡغَآئِطِ أَوۡ لَٰمَسۡتُمُ ٱلنِّسَآءَ فَلَمۡ تَجِدُواْ مَآءٗ فَتَيَمَّمُواْ صَعِيدٗا طَيِّبٗا فَٱمۡسَحُواْ بِوُجُوهِكُمۡ وَأَيۡدِيكُم مِّنۡهُۚ مَا يُرِيدُ ٱللَّهُ لِيَجۡعَلَ عَلَيۡكُم مِّنۡ حَرَجٖ وَلَٰكِن يُرِيدُ لِيُطَهِّرَكُمۡ وَلِيُتِمَّ نِعۡمَتَهُۥ عَلَيۡكُمۡ لَعَلَّكُمۡ تَشۡكُرُونَ

O you who have believed, when you rise to [perform] prayer, wash your faces and your forearms to the elbows and wipe over your heads and wash your feet to the ankles. And if you are in a state of janŒbah,[1] then purify yourselves. But if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women[2] and do not find water, then seek clean earth and wipe over your faces and hands with it. AllŒh does not intend to make difficulty for you, but He intends to purify you and complete His favor upon you that you may be grateful.


1- See footnote to 4:43.
2- i.e., had sexual intercourse.
