In the name of Allah, Most Gracious, Most Merciful.
17. And there were gathered before Sulaimân (Solomon) his hosts of jinns and men, and birds, and they all were set in battle order (marching forwards).
18. Till, when they came to the valley of the ants, one of the ants said: “O ants! Enter your dwellings, lest Sulaimân (Solomon) and his hosts crush you, while they perceive not.”
19. So he [Sulaimân (Solomon)] smiled, amused at her speech and said: “My Lord! Inspire and bestow upon 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.” 
Sura 27. An-Naml (The Ants)
