Quran: A king’s Dua

“So he [Sulaimân (Solomon)] smiled, amused at her speech and said: “My Lord! Grant me the power and ability that I may be grateful for Your Favours which You have bestowed on me and on my parents, and that I may do righteous good deeds that will please You, and admit me by Your Mercy among Your righteous slaves.”

[Chapter 27: An-Naml (The Ants) verse 19]
