Narrated Ibn 'Abbas:
That the Prophet (ﷺ) said: "Indeed the blessing descends to the middle of the food, so eat from its edges, and do not eat from its middle."[Abu 'Eisa said:] This Hadith is Hasan Sahih. It is only known through the narration of 'Ata' bin As-Sa'ib. Shu'bah and Ath-Thawri reported from 'Ata' bin As-Sa'ib.There is something about this topic from Ibn 'Umar.
