5:6O you who believe! When you rise to pray, wash your faces and your hands and arms to the elbows, and wipe your heads, and your feet to the ankles. If you had intercourse, then purify yourselves. If you are ill, or travelling, or one of you returns from the toilet, or you had contact with women, and could not find water, then use some clean sand and wipe your faces and hands with it. God does not intend to burden you, but He intends to purify you, and to complete His blessing upon you, that you may be thankful.

5:106O you who believe! When death approaches one of you, let two reliable persons from among you act as witnesses to the making of a bequest, or two persons from another people if you are travelling in the land and the event of death approaches you. Engage them after the prayer. If you have doubts, let them swear by God: “We will not sell our testimony for any price, even if he was a near relative, and we will not conceal God’s testimony, for then we would be sinners.”
