Hadith 1030

وَقَالَ الْأُوَيْسِيُّ : حَدَّثَنِي مُحَمَّدُ بْنُ جَعْفَرٍ ، عَنْ يَحْيَى بْنِ سَعِيدٍ وَشَرِيكٍ ، سَمِعَا أَنَسًا ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ رَفَعَ يَدَيْهِ حَتَّى رَأَيْتُ بَيَاضَ إِبْطَيْهِ .
The narrator Anas added that the Prophet (saws) raised his hands (during the invocation) to such an extent that the whiteness of his armpits was visible.

Hadith Commentary:
Some scholars are of the opinion that while supplicating for rain, only the imam should raise his hands, and the listeners should suffice with saying "Ameen."
Imam Bukhari rahimahullah has established that the listeners should also raise their hands and supplicate along with the imam, but when supplicating for rain, the backs of the hands should be turned towards the sky.
This is the method of supplicating in times of drought. Thus, it is narrated from Anas radi Allahu anhu that when the Messenger of Allah sallallahu alayhi wa sallam supplicated for rain, he raised both his hands towards the sky with the backs of his hands facing upwards.
