"إِذَا نَسِيَ أحدُكُمْ اسْمَ الله عَلَى طعامِه فليقُلْ إذا ذَكَرَ: باسْم الله أوّلَه وآخرَهُ" .
From 'Aishah that the Messenger of Allah ﷺ said: "When one of you eats food, then let him say: 'Bismillah.' If he forgets in the beginning, then let him say: 'Bismillah Fi Awwalihi Wa Akhirih (In the Name of Allah in its beginning and its end.)"
قَالَ رَسُولُ اللَّهِ ﷺ إِذَا أَكَلَ أَحَدُكُمْ طَعَامًا فَلْيَقُلْ بِسْمِ اللَّهِ فَإِنْ نَسِيَ فِي أَوَّلِهِ فَلْيَقُلْ بِسْمِ اللَّهِ فِي أَوَّلِهِ وَآخِرِهِ

"مَنْ نَسِيَ أَنْ يُسمِّي الله عَلَى طَعَامِهِ، فَليَقْرَأ: قُلْ هُو اللهُ أَحَد إِذَا فَرغ".
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" .
