الْحَمْـدُ للهِ حَمْـداً كَثـيراً طَيِّـباً مُبـارَكاً فيه، غَيْرَ مَكْفِيٍّ وَلا مُوَدَّعٍ وَلا مُسْتَغْـنىً عَنْـهُ رَبُّـنا
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.
