What did the Prophet Muhammad (saw) say about the reward of one's deeds depending on their intentions?
 Narrated `Umar:                     I heard the Prophet saying, "The reward of deeds depends on the intentions, so whoever emigrated for the worldly benefits or to marry a woman, his emigration was for that for which he emigrated, but whoever emigrated for the Sake of Allah and His Apostle, his emigration is for Allah and His Apostle."
