يَا أَيُّهَا الَّذِينَ آمَنُوا إِذَا قُمْتُمْ إِلَى الصَّلَاةِ فَاغْسِلُوا وُجُوهَكُمْ وَأَيْدِيَكُمْ إِلَى الْمَرَافِقِ وَامْسَحُوا بِرُءُوسِكُمْ وَأَرْجُلَكُمْ إِلَى الْكَعْبَيْنِ ۚ وَإِن كُنتُمْ جُنُبًا فَاطَّهَّرُوا ۚ وَإِن كُنتُم مَّرْضَىٰ أَوْ عَلَىٰ سَفَرٍ أَوْ جَاءَ أَحَدٌ مِّنكُم مِّنَ الْغَائِطِ أَوْ لَامَسْتُمُ النِّسَاءَ فَلَمْ تَجِدُوا مَاءً فَتَيَمَّمُوا صَعِيدًا طَيِّبًا فَامْسَحُوا بِوُجُوهِكُمْ وَأَيْدِيكُم مِّنْهُ ۚ مَا يُرِيدُ اللَّهُ لِيَجْعَلَ عَلَيْكُم مِّنْ حَرَجٍ وَلَٰكِن يُرِيدُ لِيُطَهِّرَكُمْ وَلِيُتِمَّ نِعْمَتَهُ عَلَيْكُمْ لَعَلَّكُمْ تَشْكُرُونَ (6)
(5:6) Believers! When you stand up for Prayer wash your faces and your hands up to the elbows, and wipe your heads, and wash your feet up to the ankles. *24 And if you are in the state of ritual impurity, purify yourselves (by taking a bath). *25 But if you are either ill, travelling, have satisfied a want of nature or have had contact with women and find no water then have recourse to clean earth and wipe your faces and your hands therewith. *26 Allah does not want to lay any hardship upon you; rather He wants to purify you and complete His favours upon you *27 so that you may give thanks.
*24). The explanation of this injunction by the Prophet (peace be on him) indicates that washing of the face includes rinsing one's mouth and inhaling water into the nostrils. Unless this is done the washing of the face is not considered complete. Likewise, since the ears are part of the head, 'wiping the head' includes wiping one's hands over the external and internal parts of the ears as well. Moreover, before starting to wash the other parts one should first wash one's hands so that the instruments of washing are themselves clean.
*25). Janabah (the state of major ritual impurity) - whether caused by the sexual act or merely by seminal discharge - renders it unlawful to perform the ritual Prayer and to touch the Qur'an (for further details see Surah 4, nn. 67-9 above).
*26). For explanation see Surah 4, nn. 69-70 above.
*27). Just as purity of the soul is a blessing, so is cleanliness of the body. God's favour to man can be completed only when he has received comprehensive direction in respect of both spiritual purity and physical cleanliness.
