﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا قُمْتُمْ إِلَى ٱلصَّلَوٰةِ فَٱغْسِلُوا۟ وُجُوهَكُمْ وَأَيْدِيَكُمْ إِلَى ٱلْمَرَافِقِ وَٱمْسَحُوا۟ بِرُءُوسِكُمْ وَأَرْجُلَكُمْ إِلَى ٱلْكَعْبَيْنِ ۚ وَإِن كُنتُمْ جُنُبًۭا فَٱطَّهَّرُوا۟ ۚ وَإِن كُنتُم مَّرْضَىٰٓ أَوْ عَلَىٰ سَفَرٍ أَوْ جَآءَ أَحَدٌۭ مِّنكُم مِّنَ ٱلْغَآئِطِ أَوْ لَٰمَسْتُمُ ٱلنِّسَآءَ فَلَمْ تَجِدُوا۟ مَآءًۭ فَتَيَمَّمُوا۟ صَعِيدًۭا طَيِّبًۭا فَٱمْسَحُوا۟ بِوُجُوهِكُمْ وَأَيْدِيكُم مِّنْهُ ۚ مَا يُرِيدُ ٱللَّهُ لِيَجْعَلَ عَلَيْكُم مِّنْ حَرَجٍۢ وَلَٰكِن يُرِيدُ لِيُطَهِّرَكُمْ وَلِيُتِمَّ نِعْمَتَهُۥ عَلَيْكُمْ لَعَلَّكُمْ تَشْكُرُونَ ﴾

“O YOU who have attained to faith! When you are about to pray, wash your face, and your hands and arms up to the elbows, and pass your [wet] hands lightly over your head, and [wash] your feet up to the ankles. And if you are in a state. requiring total ablution, purify yourselves. But if you are ill, or are travelling, or have just satisfied a want of nature, or have cohabited with a woman, and can find no water-then take resort to pure dust, passing therewith lightly over your face and your hands. God does not want to impose any hardship on you, but wants to make you pure, and to bestow upon you the full measure of His blessings, so that you might have cause to be grateful.”

(O ye who believe! When ye rise up for prayer) and you are not in a state of minor ritual purity, He has taught you what to do, saying: (wash your face, and your hands up to the elbows, and lightly rub your heads) as you please (and (wash) your feet) above the sole of the feet (up to the ankles. And if ye are unclean) if you are in a state of major ritual impurity, (purify yourselves) with water. (And if ye are sick) of smallpox or are wounded. This was revealed about 'Abdullah Ibn 'Awf (or on a journey, or one of you cometh from the closet) or one of you has urinated or defecated, (or ye have had (sexual) contact with women) or had sex with women, (and ye find not water) you are unable to use water, (then go to clean, high ground and rub your faces) with the first blow (and your hands) with the second blow (with some of it) i.e. some of the dust. (Allah would not place a burden) constraint (on you, but He would purify you) by means of dry ablution from minor and major ritual impurities (and would perfect His grace) His favour (upon you, that ye may give thanks) for His blessing and legal dispensation.
