Sahih Bukhari Volume 2, Book 22, Hadith Number 295.

Narated By Abu Huraira  : The Prophet (Peace and Blessings Upon Him) said, “The saying ‘Sub Han Allah’ is for men and clapping is for women.” (If something happens in the prayer, the men can invite the attention of the Imam by saying “Sub Han Allah”. And women, by clapping their hands).
