It is narrated from Yahya bin Sa'id (may Allah have mercy on him) that he asked Sayyiduna Abdullah bin Amir bin Rabi'ah (may Allah be pleased with him) about a man who performs ablution for the prayer and then eats food that has been cooked on fire: should he perform ablution? Sayyiduna Abdullah bin Amir bin Rabi'ah (may Allah be pleased with him) said: I saw my father; he did not perform ablution.
