[Machine] David, ﷺ , said: "O Lord, has anyone from your creation spent this night longer in remembrance of you than me?" So Allah revealed to him: "Yes, the frog, and Allah sent down upon him: 'O family of David, work [i.e., sincerely] in gratitude.' And few of My servants are grateful." He said: "O Lord, how can I bear Your gratitude, while it is You who bestows favors upon me, then sustains me with blessings, and then increases me in favor upon favor? So the favors are from You, O Lord, and the gratitude is from You, so how can I bear Your gratitude, O Lord?" He said: "Now you have known Me, O David, in truth of My knowledge."
