Musannaf Ibn Abi Shaybah

Habib bin Abi Thabit narrates that a man came to the Prophet ﷺ and said, "O Messenger of Allah! I have come from a tribe whose shepherd does not find rest and whose male animals do not wag their tails. Please pray for us." The Prophet ﷺ said, "O Allah! Quench Your cities and animals with water and open the doors of Your mercy." Then he prayed, "O Allah! Grant us a rain that is abundant, full of greenery, pure, with thick drops, that comes quickly, is beneficial and not harmful." So much rain fell that whoever came from any direction would say that it had rained in their area and the land had come to life.
