What did the Prophet Muhammad (saw) say about those who pray arak'ah of the afternoon or morning before the setting of the sun or rising of the sun, respectively?
 Abu Huraira reported:                      The Messenger of Allah (may peace be upon him) said: He who finds (gets) a rak'ah of the afternoon (prayer) before the setting of the sun, he in fact gets (the full prayer), and he who gets a rak'ah of the morning (prayer) before the rising of the sun he in fact gets (the full prayer).
