Ibn 'Abbas (May Allah be pleased with them) reported:
The Prophet ﷺ said, "Blessing descends upon food in its middle, so eat from the sides of the vessel and do not eat from its middle."

[At-Tirmidhi and Abu Dawud].

وعن ابن عباس رضى الله عنهما عن النبي ﷺ قال: "البركة تنزل وسط الطعام، فكلوا من حافتيه ولا تأكلوا من وسطه" .
