Mukhtasar Muslim (Abridged) 147 — Ablution from anything touched

It is narrated from 'Umar bin Abdul Aziz that 'Abdullah bin Ibrahim bin Qariz informed him that he saw Sayyiduna Abu Hurairah (may Allah be pleased with him) performing ablution in the mosque. He said: I have eaten pieces of cheese, so I am performing ablution, because I heard the Messenger of Allah (peace and blessings be upon him) say: Perform ablution after eating anything that has been cooked over fire.
