It was narrated that Anas said:

"The Prophet (ﷺ) would not raise his hands in any of his supplications except when praying for rain (Al-Istisqa')." (One of the narrators) Shu'bah said: "I said to Thabit: 'Did you hear it from Anas?' He said: 'Subhan Allah!' I said: 'Did you hear it?' He said: 'Subhan Allah!'

أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ، عَنْ شُعْبَةَ، عَنْ ثَابِتٍ الْبُنَانِيِّ، عَنْ أَنَسٍ، قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم لاَ يَرْفَعُ يَدَيْهِ فِي شَىْءٍ مِنْ دُعَائِهِ إِلاَّ فِي الاِسْتِسْقَاءِ ‏.‏ قَالَ شُعْبَةُ فَقُلْتُ لِثَابِتٍ أَنْتَ سَمِعْتَهُ مِنْ أَنَسٍ قَالَ سُبْحَانَ اللَّهِ ‏.‏ قُلْتُ سَمِعْتَهُ قَالَ سُبْحَانَ اللَّهِ ‏.‏
