That the Prophet ﷺ said: "When one of you eats food, and he drops a pieces of it, then let him remove anything suspicious from it and eat it. Do not leave it for Ash-Shaitan." He said: There is something about this from Anas.
أَنَّ النَّبِيَّ ﷺ قَالَ إِذَا أَكَلَ أَحَدُكُمْ طَعَامًا فَسَقَطَتْ لُقْمَةٌ فَلْيُمِطْ مَا رَابَهُ مِنْهَا ثُمَّ لْيَطْعَمْهَا وَلاَ يَدَعْهَا لِلشَّيْطَانِ قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ
