Purification for Prayer

Ablution

2 Samuel 12:20  King James Version (KJV)

Then David arose from the earth, and washed, and anointed himself, and changed his apparel, and came into the house of the Lord, and worshipped: then he came to his own house; and when he required, they set bread before him, and he did eat.

Exodus 40:31-32  New International Version (NIV)

31 and Moses and Aaron and his sons used it to wash their hands and feet. 32 They washed whenever they entered the tent of meeting or approached the altar, as the Lord commanded Moses.

Exodus 30:17-19  New International Version (NIV)

Basin for Washing

17 Then the Lord said to Moses, 18 “Make a bronze basin, with its bronze stand, for washing. Place it between the tent of meeting and the altar, and put water in it. 19 Aaron and his sons are to wash their hands and feet with water from it.

O you who have believed, when you rise to [perform] prayer, wash your faces and your forearms to the elbows and wipe over your heads and wash your feet to the ankles. And if you are in a state of janabah, then purify yourselves. But if you are ill or on a journey or one of you comes from the place of relieving himself or you have contacted women and do not find water, then seek clean earth and wipe over your faces and hands with it. Allah does not intend to make difficulty for you, but He intends to purify you and complete His favor upon you that you may be grateful.
