FOOD THAT HAS BEEN DROPPED H 758 "If anyone drops (even) a little bit of food he should pick it up, remove the dust from it and so on, then eat it and not leave it for satan. Neither should one wipe their hands with a napkin without licking the food from ones fingers - you do not know which part of the food has the greater blessing.'" R 758 Muslim with a chain up to Jabir who related that the Prophet, praise and peace be upon him, said this.
750- وعنه : أنَّ رسول الله صلى الله عليه وآله وسلم ، قَالَ : "إِذَا وَقَعَتْ لُقْمَةُ أحَدِكُمْ ، فَلْيأخُذْهَا فَلْيُمِطْ مَا كَانَ بِهَا مِنْ أذىً ، وَلْيَأْكُلْهَا ، وَلاَ يَدَعْهَا لِلشَّيْطَان ، وَلاَ يَمْسَحْ يَدَهُ بالمِنْدِيل حَتَّى يَلْعَقَ أصَابِعَهُ ، فَإنَّهُ لاَ يَدْري في أيِّ طَعَامِهِ البَرَكَةُ" رواه مسلم .
