Abdul Warith bin Sa'id bin Dhakwan عبد الوارث بن سعيد بن ذكوان · The Book of Purification

"The Messenger of Allah (ﷺ) said: 'I have indeed urged you with regard to the Siwak.'"

"The Messenger of Allah (ﷺ) said: 'If a man feels drowsy when he is praying, let him stop, lest he supplicate against himself without realizing.'"

"Should I perform Wudu' after eating food that I see in the Book of Allah is permissible because fire has touched it?" Abu Hurairah 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.'"
