Abu Sufyan bin al-Mughirah (may Allah have mercy on him) narrated that he visited Umm Habibah (may Allah be pleased with her), and she gave him a cup of sawiq (barley mush) to drink. He called for water and rinsed his mouth. Umm Habibah (may Allah be pleased with her) said: O my nephew, do you not perform ablution? The Prophet (peace and blessings be upon him) said: "Perform ablution from whatever the fire has altered, or whatever the fire has touched."
