Hammam reported,

Someone asked Matar Warraq, while I was sitting with him, from whom Hasan had taken the view that one performs wudu after eating what fire has altered.He replied, "He took it from Anas, and Anas took it from Abu Talha, and Abu Talha took it from the Messenger of Allah ﷺ"

حدثنا همام قال
