Significance of coming to Salat al-Jumuʿah early and listening to the khaṭīb
The Messenger of Allah ﷺ said: "When it is the day of Friday, the angels sit at the doors of the mosque, recording the people as they come. One man brought a pig, another brought a cow, another brought a sheep, another brought a chicken, another brought a sparrow, and another brought an egg. Then when the caller to prayer calls the adhan and the Imam sits on the pulpit, the books are folded up and they enter the mosque to listen to the remembrance (of Allah)."
عَنْ رَسُولِ اللهِ ﷺ أَنَّهُ قَالَ إِذَا كَانَ يَوْمُ الْجُمُعَةِ قَعَدَتِ الْمَلَائِكَةُ عَلَى أَبْوَابِ الْمَسْجِدِ فَيَكْتُبُونَ النَّاسَ مَنْ جَاءَ مِنَ النَّاسِ عَلَى مَنَازِلِهِمْ فَرَجُلٌ قَدَّمَ جَزُورًا وَرَجُلٌ قَدَّمَ بَقَرَةً وَرَجُلٌ قَدَّمَ شَاةً وَرَجُلٌ قَدَّمَ دَجَاجَةً وَرَجُلٌ قَدَّمَ عُصْفُورًا وَرَجُلٌ قَدَّمَ بَيْضَةً قَالَ فَإِذَا أَذَّنَ الْمُؤَذِّنُ وَجَلَسَ الْإِمَامُ عَلَى الْمِنْبَرِ طُوِيَتِ الصُّحُفُ وَدَخَلُوا الْمَسْجِدَ يَسْتَمِعُونَ الذِّكْرَ
