Islamic ritual washing was never for the purpose of being hygienically clean. Islamic washing was for the purpose of being ritually clean before Allah in prayer or when touching the Quran. Soap was never used five times a day before prayer as the textbook tries to imply. In fact the rules for this repeated washing called for natural water. Prohibited water types: Unclean or impure water. Water extracted from fruit and trees. Water that has changed its color, taste and smell and becomes thick because something was soaked in it. Small quantity of water in which something unclean has fallen, e.g. urine, blood, stool or wine or if some animal had died after falling into it. Water left over after drinking by animals, e.g. dogs, pigs or predatory animals. These rules prohibited the use of soap because all soap has added materials.
