Sahih Muslim Book - 7, Hadith - 1984

وَحَدَّثَنِى أَبُو الطَّاهِرِ وَحَرْمَلَةُ وَعَمْرُو بْنُ سَوَّادٍ الْعَامِرِىُّ قَالَ أَبُو الطَّاهِرِ حَدَّثَنَا وَقَالَ الآخَرَانِ أَخْبَرَنَا ابْنُ وَهْبٍ أَخْبَرَنِى يُونُسُ عَنِ ابْنِ شِهَابٍ أَخْبَرَنِى أَبُو عَبْدِ اللَّهِ الأَغَرُّ أَنَّهُ سَمِعَ أَبَا هُرَيْرَةَ يَقُولُ قَالَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- « إِذَا كَانَ يَوْمُ الْجُمُعَةِ كَانَ عَلَى كُلِّ بَابٍ مِنْ أَبْوَابِ الْمَسْجِدِ مَلاَئِكَةٌ يَكْتُبُونَ الأَوَّلَ فَالأَوَّلَ فَإِذَا جَلَسَ الإِمَامُ طَوَوُا الصُّحُفَ وَجَاءُوا يَسْتَمِعُونَ الذِّكْرَ وَمَثَلُ الْمُهَجِّرِ كَمَثَلِ الَّذِى يُهْدِى الْبَدَنَةَ ثُمَّ كَالَّذِى يُهْدِى بَقَرَةً ثُمَّ كَالَّذِى يُهْدِى الْكَبْشَ ثُمَّ كَالَّذِى يُهْدِى الدَّجَاجَةَ ثُمَّ كَالَّذِى يُهْدِى الْبَيْضَةَ ».

Abu Hurairah said: "The Messenger of Allah (s.a.w) said: 'When Friday comes, at every door of the Masjid there stand Angels who write down (the names of) those whom come first, then those who come next. When the Imam sits down, the records are closed and they come to listen to the reminder (i.e., The Khutbah) Khutba. The likeness of the one who comes early is that of one who offered a camel, then of one who offered a cow, then of one who offered a ram, then of one who offered a chicken, then of one who offered an egg.'"
