اَللَّهُمَّ عَلَى ظُهُوْرِ الْجِبَالِ وَالْآكَامِ وَبُطُوْنِ الْأَوْدِيَةِ وَمَنَابِتِ الشَّجَرِ

Allaahumma ‘alaa dhuhuril jibaali wal aakaami wa butunil awdiyati wa manaabitish shajari

O Allah! (Let it rain) on the summit of the mountain, plateau, where a variety of plants grow in the Valley. Narrated by Anas Ibn Malik (RA): A man came to the Messenger of Allah (ﷺ) and said, “O Messenger of Allah! Our animals have been destroyed and the roads have been cut off. Pray to Allah (for rain)!” The Prophet (ﷺ) prayed to Allah. As a result, it rained on us from one Jumu'ah to another Jumu'ah. Then a man came to the Prophet (ﷺ) and said, “O Messenger of Allah! Our homes have been destroyed, our roads have been cut off, and our cattle have been destroyed.” Then the Messenger of Allah (ﷺ) said: (The dua is mentioned above) Then the clouds move away from Medina in the same way that clothes are removed from the body.
