كتاب الاستسقاء
Read the English translation first, with the original Arabic directly underneath.
It was narrated that Anas bin Malik said:
"A man came to the Messenger of Allah (ﷺ) and said: 'O Messenger of Allah, the livestock have died and the routes have been cut off; pray to Allah (SWT), the Mighty and Sublime.' So the Messenger of Allah (ﷺ) prayed to Allah (SWT) and it rained from that Friday until the next. Then a man came to the Messenger of Allah (ﷺ) and said: 'The houses have been destroyed, the routes have been cut off and the livestock have died.' He said: 'O Allah, on the tops of the mountains and hills, in the bottom of the valleys and where the trees grow.' So (the rain) was lifted from Al-Madinah like a garment being removed."
اللَّهُمَّ عَلَى رُءُوسِ الْجِبَالِ وَالآكَامِ وَبُطُونِ الأَوْدِيَةِ وَمَنَابِتِ الشَّجَرِ
