Abu Sa'id al-Khudri told that when God’s messenger finished his food he said, “Praise be to God who has given us food and drink and made us Muslims.” Tirmidhi, Abu Dawud and Ibn Majah transmitted it.

وَعَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا فَرَغَ مِنْ طَعَامِهِ قَالَ: «الْحَمْدُ لِلَّهِ الَّذِي أَطْعَمَنَا وَسَقَانَا وَجَعَلَنَا مُسْلِمِينَ» . رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَابْن مَاجَه
