If the people knew the reward for pronouncing the Adhan and for standing in the first row (in the congregational prayer) and found no other way to get it except by drawing lots they would do so, and if they knew the reward of offering the Zuhr prayer early (in its stated time), they would race for it and if they knew the reward for `Isha' and Fajr prayers in congregation, they would attend them even if they were to crawl.

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."

Narrated Abu Huraira: Allah's Apostle said, "While a man was on the way, he found a thorny branch of a tree there on the way and removed it. Allah thanked him for that deed and forgave him."
