What did the Messenger of Allah (saw) utter at the end of every prayer?
 Abu Zubair reported:                      Abdullah b Zubair used to say La ilaha il-Allah at the end of every prayer like the hadith narrated by Ibn Numair and he reported it in the end, and then reported Ibn Zubair saying: The Messenger of Allah (may peace be upon him) uttered La ilaha il-Allah at the end of every prayer.
