Narrated Abu Huraira: Allah's Apostle said, "If the people knew what is the reward of making the call (for the prayer) and (of being in) the first row (in the prayer), and if they found no other way to get this privilege except by casting lots, they would certainly cast lots for it. If they knew the reward of the noon prayer, they would race for it, and if they knew the reward of the morning (i.e. Fajr) and `Isha prayers, they would present themselves for the prayer even if they had to crawl to reach there.

Narrated Abu Huraira: Allah's Apostle said, "If the people knew the reward for pronouncing the Adhan and for standing in the first row (in congregational prayers) and found no other way to get that except by drawing lots they would draw lots, and if they knew the reward of the Zuhr prayer (in the early moments of its stated time) they would race for it (go early) and if they knew the reward of `Isha' and Fajr (morning) prayers in congregation, they would come to offer them even if they had to crawl."
