O you who believe! when you rise up to prayer, wash your faces and your hands as far as the elbows, and wipe your heads and your feet to the ankles; and if you are under an obligation to perform a total ablution, then wash (yourselves) and if you are sick or on a journey, or one of you come from the privy, or you have touched the women, and you cannot find water, betake yourselves to pure earth and wipe your faces and your hands therewith, Allah does not desire to put on you any difficulty, but He wishes to purify you and that He may complete His favor on you, so that you may be grateful.

It shall be no crime in the weak, nor in the sick, nor in those who do not find what they should spend (to stay behind), so long as they are sincere to Allah and His Messenger; there is no way (to blame) against the doers of good; and Allah is Forgiving, Merciful;

There is no blame on the blind man, nor is there blame on the lame, nor is there blame on the sick, nor on yourselves that you eat from your houses, or your fathers' houses or your mothers' houses, or your brothers' houses, or your sisters' houses, or your paternal uncles' houses, or your paternal aunts' houses, or your maternal uncles' houses, or your maternal aunts' houses, or what you possess the keys of, or your friends' (houses). It is no sin in you that you eat together or separately. So when you enter houses, greet your people with a salutation from Allah, blessed (and) goodly; thus does Allah make clear to you the communications that you may understand.

There is no harm in the blind, nor is there any harm in the lame, nor is there any harm in the sick (if they do not go forth); and whoever obeys Allah and His Messenger, He will cause him to enter gardens beneath which rivers flow, and whoever turns back, He will punish him with a painful punishment.
