It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that "It was the practice of the Prophet (peace and blessings be upon him) that when the mu'adhdhin called the iqamah while he (peace and blessings be upon him) was eating, he (peace and blessings be upon him) would not stand up (for the prayer) until he had finished his meal."
