The Messenger of Allah ﷺ said: When one of you eats, he should mention Allah's name; if he forgets to mention Allah's name at the beginning, he should say: "In the name of Allah at the beginning and at the end of it."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا أَكَلَ أَحَدُكُمْ فَلْيَذْكُرِ اسْمَ اللَّهِ تَعَالَى فَإِنْ نَسِيَ أَنْ يَذْكُرَ اسْمَ اللَّهِ تَعَالَى فِي أَوَّلِهِ فَلْيَقُلْ بِسْمِ اللَّهِ أَوَّلَهُ وَآخِرَهُ  

“The Messenger of Allah ﷺ was eating food with six of his Companions when a Bedouin came and ate it all in two bites. The Messenger of Allah ﷺ said: ‘If he had said Bismillah, it would have sufficed you (all). When any one of you eats food, let him say Bismillah, and if he forgets to say Bismillah at the beginning, let him say Bismillah fi awwalihi wa akhirih (In the Name of Allah at the beginning and at the end).’”  

كَانَ رَسُولُ اللَّهِ ﷺ يَأْكُلُ طَعَامًا فِي سِتَّةِ نَفَرٍ مِنْ أَصْحَابِهِ فَجَاءَ أَعْرَابِيٌّ فَأَكَلَهُ بِلُقْمَتَيْنِ فَقَالَ رَسُولُ اللَّهِ ﷺ أَمَا أَنَّهُ لَوْ كَانَ قَالَ بِسْمِ اللَّهِ لَكَفَاكُمْ فَإِذَا أَكَلَ أَحَدُكُمْ طَعَامًا فَلْيَقُلْ بِسْمِ اللَّهِ فَإِنْ نَسِيَ أَنْ يَقُولَ بِسْمِ اللَّهِ فِي أَوَّلِهِ فَلْيَقُلْ بِسْمِ اللَّهِ فِي أَوَّلِهِ وَآخِرِهِ

كَانَ رَسُولُ اللَّهِ ﷺ يَأْكُلُ طَعَامًا فِي سِتَّةِ نَفَرٍ فَجَاءَ أَعْرَابِيٌّ فَأَكَلَهُ بِلُقْمَتَيْنِ فَقَالَ رَسُولُ اللَّهِ ﷺ «أَمَا إِنَّهُ لَوْ كَانَ سَمَّى بِاللَّهِ لَكَفَاكُمْ فَإِذَا أَكَلَ أَحَدُكُمْ طَعَامًا فَلْيَذْكُرِ اسْمَ اللَّهِ عَلَيْهِ فَإِنْ نَسِيَ فَي أَوَّلِهِ فَلْيَقُلْ بِسْمِ اللَّهِ أَوَّلَهُ وَآخِرَهُ»  

[Machine] The Messenger of Allah ﷺ used to eat in his house when a hungry Bedouin came and he fed him with two morsels of food. The Messenger of Allah ﷺ said, "If he had mentioned the name of Allah, it would have been sufficient for you all. So, when any one of you eats, let him mention the name of Allah. If he forgets to mention the name of Allah in the beginning, let him say, 'In the name of Allah' in the beginning and at the end."  

كَانَ رَسُولُ اللهِ ﷺ يَأْكُلُ فِي بَيْتِهِ فَجَاءَ أَعْرَابِيٌّ جَائِعٌ فَأَكَلَهُ بِلُقْمَتَيْنِ قَالَ رَسُولُ اللهِ ﷺ لَوْ ذَكَرَ اسْمَ اللهِ لَكَفَاكُمْ فَإِذَا أَكَلَ أَحَدُكُمْ فَلْيَذْكُرِ اسْمَ اللهِ فَإِنْ نَسِيَ أَنْ يَذْكُرَ اسْمَ اللهِ فِي أَوَّلِهِ فَلْيَقُلْ بِاسْمِ اللهِ فِي أَوَّلِهِ وَفِي آخِرِهِ  

[Machine] The Messenger of Allah ﷺ used to eat with six of his companions. Then a hungry Bedouin came and he fed him with two morsels. The Prophet ﷺ said, "If he had mentioned the name of Allah, it would have sufficed you all. So when any of you eats, let him mention the name of Allah. And if he forgets to mention it at the beginning, then let him say 'Bismillah' (in the name of Allah) at the beginning and at the end." This is the wording of the Hadith of Ruwah ibn 'Ubada.  

رَسُولَ اللهِ ﷺ كَانَ يَأْكُلُ فِي سِتَّةٍ مِنْ أَصْحَابِهِ فَجَاءَ أَعْرَابِيٌّ جَائِعٌ فَأَكَلَهُ بِلُقْمَتَيْنِ فَقَالَ النَّبِيُّ ﷺ أَمَا إِنَّهُ لَوْ ذَكَرَ اسْمَ اللهِ لَكَفَاكُمْ فَإِذَا أَكَلَ أَحَدُكُمْ فَلْيَذْكُرِ اسْمَ اللهِ فَإِنْ نَسِيَ أَنْ يُسَمِّيَ فِي أَوَّلِهِ فَلْيَقُلْ بِسْمِ اللهِ أَوَّلَهُ وَآخِرَهُ لَفْظُ حَدِيثِ رَوْحِ بْنِ عُبَادَةَ  

The Messenger of Allah ﷺ said: When one of you eats, he should mention Allah's name; if he forgets to mention Allah's name at the beginning, he should say: "In the name of Allah at the beginning and at the end of it." (Using translation from Abū Dāʾūd 3767)   

"إذا أكَلَ أحدُكُمْ طَعامًا فليذْكُرْ اسْمَ الله، فإنْ نَسِيَ أَنْ يَذْكَر اسْمَ الله في أَوَّلَه فْليقُل: بِسْم الله على أوّلَهِ وآخِرِه" .  

“The Messenger of Allah ﷺ was eating food with six of his Companions when a Bedouin came and ate it all in two bites. The Messenger of Allah ﷺ said: ‘If he had said Bismillah, it would have sufficed you (all). When any one of you eats food, let him say Bismillah, and if he forgets to say Bismillah at the beginning, let him say Bismillah fi awwalihi wa akhirih (In the Name of Allah at the beginning and at the end).’” (Using translation from Ibn Mājah 3264)   

"أَمَا إنه لو قال: بسم الله لَكَفَاكُمْ؛ فإِذا أَكَل أَحَدُكُم طعامًا فليَقُلْ: بسم اللهِ، فإِن نسى أن يقولَ: بسم الله في أوَّله، فَليَقُلْ بسم اللهِ أولَّهُ وآخرَهُ" .  

"عَنْ عَائِشَةَ قَالَتْ: كَانَ رَسُولُ اللهِ ﷺ يَأكُل الطَّعَامَ فِي سِتَّة رَهْطٍ إِذْ دَخَلَ أَعْرَابِيٌّ فَأَكَلَ مَا بَيْنَ أيديهم بِلُقْمَتَيْن فَقَالَ رَسُولُ الله ﷺ : لَوْ كَانَ ذكَرَ اسْمَ اللهِ لَكَفَاهُم، فَإِذَا أَكَلَ أَحَدُكُمْ طَعَامًا فَلْيَذكُر الله - تَعَالَى- فَإِنْ نَسى ثُم ذكَرَ فَلْيَقُلْ: بِسْم الله أَوَّله وآخره".
