Narrated Anas (RA):

The Prophet (ﷺ) was delivering the Khutbah (religious talk, sermon) while standing on a Friday when a man came into the mosque and said, "O Messenger of Allah! The livestock have died and the roads are cut off, so supplicate Allah to send us down rain." Allah's Messenger (ﷺ) raised his hands and then said, "O Allah! send us down rain, O Allah! send us down rain, O Allah! send us down rain." And the reporter mentioned the complete Hadith, which contains supplication to stop the rain. [Agreed upon].

وَعَنْ أَنَسٍ ‏- رضى الله عنه ‏- { أَنَّ رَجُلًا دَخَلَ اَلْمَسْجِدَ يَوْمَ اَلْجُمُعَةِ, وَالنَّبِيُّ ‏- صلى الله عليه وسلم ‏-قَائِمٌ يَخْطُبُ.‏ فَقَالَ: يَا رَسُولَ اَللَّهِ, هَلَكَتِ اَلْأَمْوَالُ, وَانْقَطَعَتِ اَلسُّبُلُ, فَادْعُ اَللَّهَ] عَزَّ وَجَلَّ] يُغِيثُنَا, فَرَفَعَ يَدَيْهِ, ثُمَّ قَالَ:

اَللَّهُمَّ أَغِثْنَا, اَللَّهُمَّ أَغِثْنَا.‏.‏.‏
