Sayyidah Umm Salamah (may Allah be pleased with her) states: The Prophet (peace and blessings be upon him) said: "When the evening meal is served and the time for prayer has also come, then eat first."
Imam Ahmad, Imam Abu Ya'la and Imam al-Tabarani in al-Mu'jam al-Kabir recorded this narration, and its narrators are thiqat (trustworthy); they heard from one another.
