It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: If people knew what reward there is in the call to prayer (adhan) and in the first row (of prayer), and then they could not obtain these except by drawing lots, they would certainly draw lots for them. And if people knew how much reward there is in coming early to the prayer, they would race to it. And if they knew how much reward there is in the Isha and Fajr prayers, they would attend them even if they had to crawl.
