A Hadith on Jummah

Rasulallah (sallalhu'alayhi wasalam) said: "On the day of Jummah, the angels stand at the entrance of that Masjid in which Jummah salaat is to be offered. They write down the name of the person who enters the Masjid first, and thereafter the name of the person who follows, and they continue doing this. The person who entered first will receive the reward of sacrificing a camel in the path of Allah; the one who followed him will get the reward of sacrificing a cow, thereafter a chicken, thereafter the reward of giving an egg as charity in the path of Allah. Once the khutbah commences, the angels close the register and begin listening to the khutbah. “ (Bukhari and Muslim)
