The Prophet ﷺ said: When one of you eats, he must not eat from the top of the dish, but should eat from the bottom; for the blessing descends from the top of it.
عَنِ النَّبِيِّ ﷺ قَالَ إِذَا أَكَلَ أَحَدُكُمْ طَعَامًا فَلاَ يَأْكُلْ مِنْ أَعْلَى الصَّحْفَةِ وَلَكِنْ لِيَأْكُلْ مِنْ أَسْفَلِهَا فَإِنَّ الْبَرَكَةَ تَنْزِلُ مِنْ أَعْلاَهَا
