Maulana Mohammad Ali:
O you who believe, when you rise 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. And if you are under an obligation, then wash (yourselves). And if you are sick or on a journey, or one of you comes from the privy, or you have had contact with women and you cannot find water, betake yourselves to pure earth and wipe your faces and your hands therewith. Allah desires not to place a burden on you but He wishes to purify you, and that He may complete His favour on you, so that you may give thanks.
Surah Al Maidah (The Table Spread with Food) Ayat 7
