Questions and Answers
51Question: With reference to ablutions, it hath been revealed, “Let him that findeth no water for ablution repeat five times the words ‘In the Name of God, the Most Pure, the Most Pure’”: is it permissible to recite this verse in times of bitter cold, or if the hands or face be wounded?
Answer: Warm water may be used in times of bitter cold. If there are wounds on the face or hands, or there be other reasons such as aches and pains for which the use of water would be harmful, one may recite the appointed verse in place of the ablution.
