Salat - The Muslim Prayer Book — Page 12
12 S al a t —The Muslim Prayer Book on a mount, train, boat or plane, one should say one’s Prayers facing in the same direction towards which one is moving, or indeed any convenient position will be acceptable. ABLUTION The word ablution applies to washing some parts of the body preparatory to the performance of Prayer. This is a prerequisite which must be fulfilled, otherwise the Prayer will not be considered valid. The Hadith clearly instructs that one should wash one’s hands three times with water and then clean one’s mouth by rinsing with water three times. Then, the nose should be internally cleaned by pushing a little water into the nostrils three times.
