The people used to attend the Friday prayer from their houses and from the suburbs of Medina.  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ كَانَ النَّاسُ يَنْتَابُونَ الْجُمُعَةَ مِنْ مَنَازِلِهِمْ وَمِنَ الْعَوَالِي  

The Prophet ﷺ said: The Friday prayer is obligatory on him who hears the call. Abu Dawud said: This tradition has been transmitted by a group of narrators from Sufyan. They did not narrate it as a statement of the Prophet ﷺ; only Qabisah has transmitted it as saying of the Prophet ﷺ.  

عَنْ أَبِي سَلَمَةَ بْنِ نُبَيْهٍ عَنْ عَبْدِ اللَّهِ بْنِ هَارُونَ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو عَنِ النَّبِيِّ ﷺ قَالَ الْجُمُعَةُ عَلَى كُلِّ مَنْ سَمِعَ النِّدَاءَ
