The Messenger of Allah ﷺ said, "When dinner is served, begin with it before performing the Maghrib prayer, and do not rush through your meal."
أن رسول الله ﷺ قال: إذا قدم العشاء، فابدءوا به قبل أن تصلوا صلاة المغرب، ولا تعجلوا عن عشائكم.
Bukhari narrated it in adhan (672), and Muslim in mosques (557), both from the hadith of Ibn Shihab, from Anas bin Malik, who mentioned it.
