[Machine] The Messenger of Allah ﷺ used to raise his hands in supplication until the whiteness of his armpits was visible. Shu'bah said, "So I went to 'Ali bin Zaid and mentioned this to him, and he said, 'He only did that for seeking rain.' So I said to him, 'Did you hear it from Anas?' He said, 'Subhan Allah!' I said, 'Did you hear it from Anas?' He said, 'Subhan Allah!' Abu 'Abdullah (al-Bukhari) said: And this Hadith has been narrated from Qatadah from Anas."  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ «يَرْفَعُ يَدَيْهِ فِي الدُّعَاءِ حَتَّى يُرَى بَيَاضُ إِبْطَيْهِ» قَالَ شُعْبَةُ فَأَتَيْتُ عَلِيَّ بْنَ زَيْدٍ فَذَكَرْتُ لَهُ ذَلِكَ فَقَالَ إِنَّمَا يُرِيدُ فِي الِاسْتِسْقَاءِ فَقُلْتُ لَهُ أَسَمِعْتَهُ مِنْ أَنَسٍ؟ قَالَ سُبْحَانَ اللهِ قُلْتُ أَسَمِعْتَهُ مِنْ أَنَسٍ؟ قَالَ سُبْحَانَ اللهِ قَالَ أَبُو عَبْدِ الرَّحْمَنِ وَقَدْ رَوَى هَذَا الْحَدِيثَ قَتَادَةُ عَنْ أَنَسٍ
