In Sahih al-Bukhari it is recorded that the Messenger of Allah (sallAllahu 'alayhi wa sallam) used to supplicate; اللَّهُمَّ لَكَ الْحَمْدُ غَيْرَ مَكْفِيَ وَلَا مُوَدَّعٍ وَلَا مُسْتَغْنًى عَنْهُ رَبَّنَا (O Allah ! All praise is due to You, without being able to sufficiently thank You, nor ever wish to be cutoff from You, nor ever feeling rich from relying on You; our Lord!)
It was reported that Prophet Dawud, 'alayhis-salaam, used to say in his supplication, "O Lord! How can I ever duly thank You, when my thanking You is also a favor from You to me?” Allah the Exalted answered him, "Now, you have thanked Me sufficiently, O Dawud," meaning, `when you admitted that you will never be able to duly thank Me.’
