I heard Allah's Apostle ﷺ as saying: The Satan is present with any one of you in everything he does; he is present even when he eats food; so if any one of you drops a mouthful he should remove away anything filthy on it and eat it and not leave for the devil; and when he finishes (food) he should lick his fingers, for he does not know in what portion of his food the blessing lies.  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ إِنَّ الشَّيْطَانَ يَحْضُرُ أَحَدَكُمْ عِنْدَ كُلِّ شَىْءٍ مِنْ شَأْنِهِ حَتَّى يَحْضُرَهُ عِنْدَ طَعَامِهِ فَإِذَا سَقَطَتْ مِنْ أَحَدِكُمُ اللُّقْمَةُ فَلْيُمِطْ مَا كَانَ بِهَا مِنْ أَذًى ثُمَّ لْيَأْكُلْهَا وَلاَ يَدَعْهَا لِلشَّيْطَانِ فَإِذَا فَرَغَ فَلْيَلْعَقْ أَصَابِعَهُ فَإِنَّهُ لاَ يَدْرِي فِي أَىِّ طَعَامِهِ تَكُونُ الْبَرَكَةُ  

When any one of you drops a mouthful he should remove anything filthy from it and then eat it, and should not leave it for the Satan. He also commanded us that we should wipe the dish saying: You do not know in what portion of your food the blessing lies.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا أَكَلَ طَعَامًا لَعِقَ أَصَابِعَهُ الثَّلاَثَ قَالَ وَقَالَ إِذَا سَقَطَتْ لُقْمَةُ أَحَدِكُمْ فَلْيُمِطْ عَنْهَا الأَذَى وَلْيَأْكُلْهَا وَلاَ يَدَعْهَا لِلشَّيْطَانِ وَأَمَرَنَا أَنْ نَسْلُتَ الْقَصْعَةَ قَالَ فَإِنَّكُمْ لاَ تَدْرُونَ فِي أَىِّ طَعَامِكُمُ الْبَرَكَةُ  

"When the Prophet ﷺ ate, he would lick his three fingers, and he said: 'If one of you drops a piece (of food) then let him remove any harm (dirt) from it and eat it, and do not leave it for Ash-Shaitan.' And he would order us to finish (clean) the dish. And he said: 'Indeed you do not know in which part of your food is the blessing.'  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا مَا أَكَلَ طَعَامًا لَعِقَ أَصَابِعَهُ الثَّلاَثَ وَقَالَ إِذَا مَا وَقَعَتْ لُقْمَةُ أَحَدِكُمْ فَلْيُمِطْ عَنْهَا الأَذَى وَلْيَأْكُلْهَا وَلاَ يَدَعْهَا لِلشَّيْطَانِ وَأَمَرَنَا أَنْ نَسْلُتَ الصَّحْفَةَ وَقَالَ إِنَّكُمْ لاَ تَدْرُونَ فِي أَىِّ طَعَامِكُمُ الْبَرَكَةُ  

When any one of you drops a mouthful he should remove anything filthy from it and then eat it, and should not leave it for the Satan. He also commanded us that we should wipe the dish saying: You do not know in what portion of your food the blessing lies. (Using translation from Muslim 2034)  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا أَكَلَ طَعَامًا لَعِقَ أَصَابِعَهُ الثَّلَاثَ وَقَالَ إِذَا مَا وَقَعَتْ لُقْمَةُ أَحَدِكُمْ فَلْيُمِطْ عَنْهَا الْأَذَى وَلْيَأْكُلْهَا وَلَا يَدَعْهَا لِلشَّيْطَانِ وَأَمَرَنَا أَنْ نَسْلِتَ الصَّحْفَةَ وَقَالَ إِنَّكُمْ لَا تَدْرُونَ فِي أَيِّ طَعَامِكُمُ الْبَرَكَةَ  

When any one of you drops a mouthful he should remove anything filthy from it and then eat it, and should not leave it for the Satan. He also commanded us that we should wipe the dish saying: You do not know in what portion of your food the blessing lies. (Using translation from Muslim 2034)   

أَنَّ النَّبِيَّ ﷺ كَانَ يَلْعَقُ أَصَابِعَهُ الثَّلَاثَ إِذَا أَكَلَ وَقَالَ إِذَا وَقَعَتْ لُقْمَةُ أَحَدِكُمْ فَلْيُمِطْ عَنْهَا الْأَذَى وَلْيَأْكُلْهَا وَلَا يَدَعْهَا لِلشَّيْطَانِ وَلْيَسْلُتْ أَحَدُكُمُ الصَّحْفَةَ فَإِنَّكُمْ لَا تَدْرُونَ فِي أَيِّ طَعَامِكُمُ الْبَرَكَةَ  

When any one of you drops a mouthful he should pick it up and remove any of the filth on it, and then eat it, and should not leave it for the Satan, and should not wipe his hand with towel until he has licked his fingers, for he does not know in what portion of the food the blessing lies. (Using translation from Muslim 2033b)   

قَالَ رَسُولُ اللهِ ﷺ إِذَا سَقَطَتْ لُقْمَةُ أَحَدِكُمْ فَلْيُمِطْ مَا كَانَ بِهَا مِنْ أَذًى ثُمَّ لِيَأْكُلْهَا وَلَا يَدَعْهَا لِلشَّيْطَانِ وَلَا يَمْسَحْ أَحَدُكُمْ يَدَهُ بِالْمِنْدِيلِ حَتَّى يَلْعَقَ أَصَابِعَهُ أَوْ يُلْعِقَهَا فَإِنَّهُ لَا يَدْرِي فِي أَيِّ طَعَامِهِ الْبَرَكَةُ  

[Machine] The Messenger of Allah ﷺ said, "If a morsel of food falls, one of you should remove any dirt from it and eat it, and not leave it for Satan. And wipe your plates, for blessing cannot be determined in which of your meals it will be found."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «إِذَا سَقَطَتْ لُقْمَةُ أَحَدِكُمْ فَلْيُمِطِ الْأَذَى عَنْهَا وَلْيَأْكُلْهَا وَلَا يَدَعْهَا لِلشَّيْطَانِ وَأَسْلِتُوا الصَّحْفَةَ فَإِنَّهُ لَا يُدْرَى فِي أَيِّ طَعَامِكُمْ تَكُونُ الْبَرَكَةُ»  

If the morsel of one of you falls down, he should wipe away anything injurious on it and eat it and not leave it for the devil. And he ordered us to clean the dish, for one of you does not leave it for the devil. And he ordered us to clean the dish, for one of you does not know in what part of his food the blessing lies. (Using translation from Abū Dāʾūd 3845)   

أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا أَكَلَ طَعَامًا لَعِقَ أَصَابِعَهُ الثَّلَاثَ وَقَالَ «إِذَا سَقَطَتْ لُقْمَةُ أَحَدِكُمْ فَلْيُمِطْ عَنْهَا الْأَذَى وَلْيَأْكُلْهَا وَلَا يَدَعْهَا لِلشَّيْطَانِ»  

If the morsel of one of you falls down, he should wipe away anything injurious on it and eat it and not leave it for the devil. And he ordered us to clean the dish, for one of you does not leave it for the devil. And he ordered us to clean the dish, for one of you does not know in what part of his food the blessing lies. (Using translation from Abū Dāʾūd 3845)   

أَنَّ رَسُولَ اللهِ ﷺ كَانَ إِذَا أَكَلَ طَعَامًا لَعِقَ أَصَابِعَهُ الثَّلَاثَ وَقَالَ إِذَا سَقَطَتْ لُقْمَةُ أَحَدِكُمْ فَلْيُمِطْ عَنْهَا الْأَذَى وَلْيَأْكُلْهَا وَلَا يَدَعْهَا لِلشَّيْطَانِ وَأَمَرَنَا أَنْ نَسْلُتَ الصَّحْفَةَ وَقَالَ إِنَّ أَحَدَكُمْ لَا يَدْرِي فِي أِيِّ طَعَامِهِ يُبَارَكُ لَهُ  

"إِذَا وقعتْ اللقمةُ مِنْ أحدكُمْ فلْيَأخُذْها فْليُمطْ عَنْها الأذَى، وليأكُلها، ولا يَدعْها للشّيطانِ وليسْلِتْ أحدُكُمْ الصَّحْفَةَ، فإِنّكمْ لا تدْرُون في أيِّ طَعامِكُمْ البركة".  

"إذا سَقَطتْ لُقمةُ أحدِكُمْ فْليُمطْ عْنها الأذى ولْيأكُلْها، ولا يدَعْها للشيطان، ولْيَسْلُت أحدُكم الصحفةَ؛ فإِنَّكُمْ لا تدرُون في أيِّ طَعَامِكُمْ تَكُونُ البركةُ".
