The Supplication When Praying For Rain
Sahih Muslim
وَحَدَّثَنَا هَارُونُ بْنُ سَعِيدٍ الأَيْلِيُّ، حَدَّثَنَا ابْنُ وَهْبٍ، حَدَّثَنِي أُسَامَةُ، أَنَّ حَفْصَ بْنَ، عُبَيْدِ اللَّهِ بْنِ أَنَسِ بْنِ مَالِكٍ حَدَّثَهُ أَنَّهُ، سَمِعَ أَنَسَ بْنَ مَالِكٍ، يَقُولُ جَاءَ أَعْرَابِيٌّ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم يَوْمَ الْجُمُعَةِ وَهُوَ عَلَى الْمِنْبَرِ . وَاقْتَصَّ الْحَدِيثَ وَزَادَ فَرَأَيْتُ السَّحَابَ يَتَمَزَّقُ كَأَنَّهُ الْمُلاَءُ حِينَ تُطْوَى .
'Ubaidullah b. Anas b. Malik heard (his father) Anas b. Malik as saying: A bedouin came to the Messenger of Allah (ﷺ) on Friday as he was (delivering the sermon on his) pulpit; and the rest of the hadith is the same but with this addition:" I saw the cloud clearing just as a sheet is folded."
