یٰۤاَیُّہَا الَّذِیْنَ اٰمَنُوْۤا اِذَا قُمْتُمْ  اِلَی الصَّلٰوۃِ فَاغْسِلُوْا وُجُوْہَکُمْ وَ اَیْدِیَکُمْ  اِلَی الْمَرَافِقِ وَ امْسَحُوْا بِرُءُوْسِکُمْ وَ اَرْجُلَکُمْ  اِلَی الْکَعْبَیْنِ ؕ وَ اِنْ کُنْتُمْ جُنُبًا فَاطَّہَّرُوْا ؕ وَ اِنْ کُنْتُمْ مَّرْضٰۤی اَوْ عَلٰی سَفَرٍ  اَوْ جَآءَ  اَحَدٌ مِّنْکُمْ  مِّنَ الْغَآئِطِ اَوْ لٰمَسْتُمُ النِّسَآءَ  فَلَمْ  تَجِدُوْا مَآءً فَتَیَمَّمُوْا صَعِیْدًا طَیِّبًا فَامْسَحُوْا بِوُجُوْہِکُمْ وَ اَیْدِیْکُمْ مِّنْہُ ؕ مَا یُرِیْدُ اللّٰہُ لِیَجْعَلَ عَلَیْکُمْ مِّنْ حَرَجٍ وَّ لٰکِنْ یُّرِیْدُ لِیُطَہِّرَکُمْ وَ لِیُتِمَّ نِعْمَتَہٗ عَلَیْکُمْ لَعَلَّکُمْ تَشْکُرُوْنَ (۶)

O believers! When you intend to stand up for Salah; so, wash your faces, and your hands up to (i.e. including) the elbows, and pass wet hands (i.e. perform Massah - wipe) over your heads and wash your feet up to (i.e. including) the ankles. And if you need to have an obligatory bath; so, clean yourselves thoroughly, and if you are sick or on a journey, or if any of you comes having responded to the call of nature, or you have had intercourse with your wives; and in these conditions you do not find water, so, perform Tayammum with pure sand; hence, rub your faces therewith and your hands (i.e. including the forearms as well as the elbows). Allah does not will to place any hardship upon you. Yes; He wills to purify you totally and complete His Favour upon you (so) that you may be grateful.^[1]

This sacred verse allowed for tayammum to be performed when no water was available for wudu. The Companions رَضِیَ اللهُ عَنْهُم exclaimed, مَا ھِیَ بِاَوَّلِ بَرَکَتِکُمْ یَا آلَ  اِبِی بَکْر - “O offspring of Abū Bakr رَضِىَ اللهُ عَـنْهُ! This is not your first blessing!” (Meaning, the Muslims have received many blessings through you)^[2]
