Ibn ‘Abbas said: “Should I perform Wudu after eating food that I see in the Book of Allah is permissible because fire has touched it?” Abu Hurairah (RA) gathered some pebbles and said: “I bear witness (as many times as) the number of these pebbles, that the Messenger of Allah ﷺ said: ‘Perform Wudu’ from that which has been touched by fire.” (Sahih)
