Sahih al-Bukhari 929
Narrated Abu Huraira:
The Prophet (ﷺ) said, "When it is a Friday, the angels stand at the gate of the mosque and keep on writing 
the names of the persons coming to the mosque in succession according to their arrivals. The example 
of the one who enters the mosque in the earliest hour is that of one offering a camel (in sacrifice). The 
one coming next is like one offering a cow and then a ram and then a chicken and then an egg 
respectively. When the Imam comes out (for Jumua prayer) they (i.e. angels) fold their papers and 
listen to the Khutba."
حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي عَبْدِ اللَّهِ الأَغَرِّ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏
"‏ إِذَا كَانَ يَوْمُ الْجُمُعَةِ، وَقَفَتِ الْمَلاَئِكَةُ عَلَى باب الْمَسْجِدِ يَكْتُبُونَ الأَوَّلَ فَالأَوَّلَ، وَمَثَلُ الْمُهَجِّرِ كَمَثَلِ الَّذِي يُهْدِي بَدَنَةً، ثُمَّ كَالَّذِي يُهْدِي بَقَرَةً، ثُمَّ كَبْشًا، ثُمَّ دَجَاجَةً، ثُمَّ بَيْضَةً، فَإِذَا خَرَجَ الإِمَامُ طَوَوْا صُحُفَهُمْ، وَيَسْتَمِعُونَ الذِّكْرَ ‏"‏‏.‏
