Mukhtasar Muslim

Narrated from Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: If people knew the reward and merit of the call to prayer and standing in the first row, and there was no other way but to draw lots, then they would draw lots for it. And if people knew the virtue of offering prayer at its earliest time, they would compete with each other for it. And if they knew the excellence of 'Isha and Fajr prayers, they would come to them even if they had to crawl.
