They said if someone fell into water without his option or he entered into water just to enjoy himself, to cool himself or to clean himself or just to join the others and then water covered all his organs of wudu’, he could offer the prayer with this wudu’ even if he was unbeliever when he entered into water and then he became a Muslim when he left the water. They didn’t consider believing in Islam as a condition for the validity of wudu’.

They stipulated the intention for the validity of tayammum because soil didn’t purify in its nature but its purification was a devotional act so the validity of tayammum required an intention. So was about performing wudu’ and ghussl with date-juice or the leftover water, from which a donkey or a mule drank, because the purity of this date-juice and such leftover water was devotional like the soil in tayammum. They went too far in detailing wudu’ and ghussl.
