Sahih Muslim Book 004, Hadith Number 2123.
Chapter : Funeral prayer in the mosque.
'Abbad b. 'Abdullah b. Zubair reported that 'Aisha ordered the bier of Sa'd b. Abu Waqqas to be brought into the mosque so that she should pray for him. The people disapproved this (act) of hers. She said: How soon the people have forgotten that the Messenger of Allah (may peace be upon him) offered not the funeral prayer of Suhail b al-Baida' but in a mosque.
