Observing the Sunnah and the manners of its obedience
التاسع: عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ، أَمَرَ بِلَعْقِ الأَصَابِعِ وَالصَّحْفَةِ وَقَالَ: "إِنَّكُمْ لاَ تَدْرُونَ فِي أيها البركة" ((رَوَاهُ مُسلم)). وَفِي رِوَايَةٍ لَهُ: " إِذَا وَقَعَتْ لُقْمَةُ أَحَدِكُمْ . فَلْيَأْخُذْهَا فَلْيُمِطْ ماكان بِهَا مِنْ أَذًى، وَلْيَأْكُلْهَا، وَلاَ يَدَعْهَا لِلشَّيْطَانِ، وَلاَ يَمْسَحْ يَدَهُ بِالْمِنْدِيلِ حَتَّى يَلْعَقَ أَصَابِعَهُ، فَإِنَّهُ لاَ يَدْرِي فِي أي طَعَامِهِ الْبَرَكَةُ". وَفِي رِوَايَةٍ لَهُ: "إن الشَّيْطَانَ يَحْضُرُ أَحَدَكُمْ عِنْدَ كُلِّ شيء مِنْ شَأْنِهِ حَتَّى يَحْضُرَهُ عِنْدَ طَعَامِهِ، فَإِذَا سَقَطَتْ مِنْ أَحَدِكُمُ اللُّقْمَةُ فَلْيُمِطْ مَا كَانَ بِهَا مِنْ أَذًى ، فليأكلها، ولا يدعها للشيطان".
Jabir (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) commanded the licking of fingers (after eating) and the cleaning of the dish, saying: "You do not know in what portion the Blessing (of Allah) lies". [Muslim]. In another narration, Jabir said: Messenger of Allah (ﷺ) said, "When a morsel of any of you falls down, you should pick it up and remove any dirt or dust on it and then eat it; and don't leave it for Satan; and do not wipe your hand with the towel until you have licked your fingers, for you do not know in what portion of the food the Barakah* (of Allah) lies". * Barakah is the abundance of goodness and its continuity.
