Sunan Abu Dawood, Chapter: Prayer (Kitab Al-Salat): Details of Commencing Prayer

I remember from the Apostle of Allah (peace_be_upon_him) two periods of silence. Said said: We asked Qatadah: What are those two periods of silence? He said: (one) when he began his prayer, and (one) when he finished the recitation. Then he added: When he finished reciting (the closing verse of the Fatihah): "Not of those with whom Thou art angry, nor of who go astray."
