Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Prophet Muhammad (peace and blessings be upon him) came after relieving himself and began to eat food. It was submitted to him, "Are you eating before performing ablution?" The Prophet Muhammad (peace and blessings be upon him) replied: "Am I about to pray that I should perform ablution?"
