Muwatta Imam Malik Book of Asking for Rain, Hadith 2
Yahya related to me from Malik from Yahya ibn Said from Amr ibn Shuayb that the Messenger of Allah ﷺ said, when he asked for rain, "O Allah, give water to Your slaves and Your animals, and spread Your mercy, and give life to Your dead land."
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا اسْتَسْقَى قَالَ " اللَّهُمَّ اسْقِ عِبَادَكَ وَبَهِيمَتَكَ وَانْشُرْ رَحْمَتَكَ وَأَحْىِ بَلَدَكَ الْمَيِّتَ " .
