Messenger of Allah (ﷺ), used to say:

اَللَّهُمَّ اسْقِ عِبَادَكَ، وَبَهَائِمَكَ، وَانْشُرْ رَحْمَتَكَ، وَأَحْيِي بَلَدَكَ الْمَيِّتَ

Allahum-masqi 'ibaadaka, wa bahaa'imaka, wanshur rahmataka, wa 'ahyi baladakal-mayyita

O Allah, give water to Your slaves, and Your livestock, and spread Your mercy, and revive Your dead land.

Reference: Hasan (Albani). Abu Dawud: 1176
