The Prophet (ﷺ) used to say while lifting the Dastarkhan:

اَلْحَمْدُ لِلَّهِ حَمْدًا كَثِيرًا طَيِّبًا مُبَارَكًا فِيهِ، غَيْرَ مَكْفِيٍّ وَلَا مُوَدَّعٍ، وَلَا مُسْتَغْنًى عَنْهُ رَبَّنَا

Alhamdu lillaahi hamdan katheeran tayyiban mubaarakan feehi, ghayra [makfiyyin wa laa] muwadda'in, wa laa mustaghnan 'anhu Rabbanaa

All praise is to Allah, praise in abundance, good and blessed. It cannot [be compensated for, nor can it] be left, nor can it be done without, our Lord.
