Ibn Saeed bin Mughira once visited Hazrat Umm Habibah, so she filled a bowl with sattu and gave it to him to drink. Then Ibn Saeed took some water and only rinsed his mouth. Hazrat Umm Habibah said, "Nephew, why do you not perform ablution? The Prophet (peace be upon him) said: After eating something cooked on fire, perform ablution."
