Musannaf Ibn Abi Shayba 21:367

Waki’ narrated to us, from Mis’ar, from Zayd al-‘Ammi, from Abu al-Siddiq al-Naji, that Sulayman ibn Dawud went out with the people to pray for rain. He passed by an ant lying on its back, raising its legs toward the sky, and it was saying: "O Allah, we are a creation from Your creation; we have no independence from Your provision. So either You give us water, or You destroy us." Sulayman said to the people: "Return, for you have been given water through the supplication of others."
