It was narrated that 'Abdullah bin Ibrahim bin Qariz said:
"I saw Abu Hurairah performing Wudu' on the roof of the Masjid ans he said: 'I ate some tough cheese, so I performed Wudu' because of that. I heard the Messenger of Allah (ﷺ) commanding us to do Wudu' from that which has been touched by fire.'" (JA)
