The Second Rak'ah
"When he (sallallaahu 'alaihi wa sallam) got up for the second rak'ah, he would commence with All Praise be to Allaah (Faatihah 1:1), without pausing."170
He would perform this rak'ah exactly as he performed the first, except that he would make it shorter than the first, as before.
The Obligation of Reciting Soorah al-Faatihah in every Rak'ah
He ordered "the one who prayed badly" to recite al-Faatihah in every rak'ah, when he said to him after ordering him to recite it in the first rak'ah171, then do that throughout your prayer172 (in one narration: in every rak'ah).173 He also used to say, There is recitation in every rak'ah.174
