Sunan Ibn Majah Book 5, Hadith 131
“If food is served and the Iqamah for prayer is given, then
start
with the food.”
“When the Messenger of Allah (ﷺ) said the Salam, the women would stand up when he finished his Taslim, and he would stay where he was for a little while before standing up. (i.e. to depart).”
“The Messenger of Allah (ﷺ) said: ‘If food is served and the Iqamah for prayer is given, then start with the food.”
He said: "Ibn 'Umar ate dinner one night while he could hear the Iqamah."
