Muslim bin Yasar al-Masri al-Tanbadhi مسلم بن يسار المصري أبو عثمان الطنبذي · The Book on Food

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." 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.
