O you who acknowledge, when you rise to attend the contact prayer, then wash your faces and your hands up to the elbows, and wipe your heads and your feet to the ankles; and if you have had intercourse, then you shall bathe. If you are ill, or traveling, or you have excreted feces, or you have had sexual contact with the women, and you could not find water, then you shall do ablution from clean soil; you shall wipe your faces and your hands. God does not want to make any hardship over you, but He wants to cleanse you and to complete His blessings upon you that you may be appreciative.
Translation endnotes
[5:6] The Quran, which is complete, and sufficiently detailed, describes ablution in four steps. We should not add more steps to it. The Arabic word, which is translated "your feet," can be read in two different ways, arjulakum or arjulikum, changing its reference verb and thus changing the meaning from "wash your feet" to "wipe your feet." One may prefer one of these readings, or follow both depending on occasion. See 4:43. The Bible contains various references to ablution (Deuteronomy 23:10-15; Exodus 30:17-21; Leviticus 8:6; Psalms 26:6; Hebrews 10:22). The Bible also refers to Jesus being critical of Pharisees for being too scrupulous regarding the formalities of ablution, exactly like today's Sunnis and Shiites are (Matthew 23:25).
