What can we learn from the example of the Prophet Muhammad (saw) when he offered two rak`at of prayer at Mina, as well as Abu Bakr and Umar (peace be upon them all)?
 Narrated `Abdullah bin Mas`ud:                     I offered (only a) two rak`at prayer with the Prophet (at Mina), and similarly with Abu Bakr and with `Umar, and then you d offered in opinions. Wish that I would be lucky enough to have two of the four rak`at accepted (by Allah).
