أَفَلَا يَتَدَبَّرُونَ ٱلْقُرْءَانَ ۚ وَلَوْ كَانَ مِنْ عِندِ غَيْرِ ٱللَّهِ لَوَجَدُوا۟ فِيهِ ٱخْتِلَٰفًۭا كَثِيرًۭا
Will they not then ponder on the Qur'an? If it had been from other than Allah they would have found therein much incongruity.
Surah An-Nisaa(4:82)
Sahih al-Bukhari
Invoking Allah for Rain (Istisqaa)
Chapter: If the people request the Imam to invoke Allah for rain, the Imam should not refuse
Narrated Anas bin Malik:
A man came to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! Livestock are destroyed and the roads are cut off; so please invoke Allah." So Allah's Messenger (ﷺ) prayed for rain and it rained from that Friday till the next Friday. Then a man came to the Prophet (p.b.u.h) and said, "O Allah's Messenger (ﷺ)! The houses have collapsed, roads are cut off and the livestock are destroyed." So Allah's Messenger (ﷺ) said, "O Allah ! (Let it rain) on the tops of the mountains, on the plateaus, in the valleys and over the places where trees grow." So the clouds cleared away from Medina as clothes are taken off.
