Muslim

English Commentary:
1:
The wording ((فِی الدُّعَاءِ)) does not appear in Sahih Muslim.
The author has used this wording to argue that one should not raise the hands during supplication (du'a) in the Friday sermon (khutbah).
According to the narration in Muslim, the meaning of the hadith is that one should not excessively raise the hands during the khutbah. As for what is narrated in Sahih al-Bukhari from Anas radi Allahu anhu, that the Prophet sallallahu alayhi wa sallam, during the khutbah, supplicated for rain and raised his hands—
then, according to some of the imams, this was a supplication for istisqa (seeking rain), and that is why the hands were raised.
The correct view is that ‘Ammarah ibn Ruwaybah warned, in an unrestricted manner, about excessive movement of the hands during the khutbah.

1104. Commentary:
For the khateeb to wave his hands while addressing the people during the sermon is contrary to the Sunnah and against the etiquette of Jumu‘ah. Only pointing with the index finger is established. As for the argument that raising the hands for supplication during the sermon is prohibited—even though some narrators have inclined towards this view—this argument is weak. Because it is established from the Prophet sallallahu alayhi wa sallam that he raised his hands and supplicated for rain (istisqa’) during the sermon.
