Prayer (Kitab Al-Salat): Details of Commencing Prayer

Dawud :: Book 3 : Hadith 1033

Narrated Thawban:

The Prophet (peace_be_upon_him) said: For each forgetfulness there are two prostrations after giving the salutation.

No one except Amr (ibn Uthman) mentioned the words "from his father" (in the chain AbdurRahman ibn Jubayr ibn Nufayr from Thawban).
