Hazrat Awza'i (may Allah have mercy on him) says that Hazrat Usman bin Abi Sawdah (may Allah have mercy on him) once recited this verse { وَالسَّابِقُونَ السَّابِقُونَ أُولَئِکَ الْمُقَرَّبُونَ } and then said that it refers to those people who are the first to go to the mosque and the first to set out in the way of Allah.
