[Machine] "Whoever catches the sermon, then Friday prayer is two units of prayer (rak'at). And whoever does not catch it, then they should pray four units (rak'at). And whoever does not catch the unit of prayer (rak'ah), they should not rely on prostration until they catch the unit of prayer (rak'ah)."  

الطبراني:٩٥٤٨حَدَّثَنَا مُحَمَّدُ بْنُ النَّضْرِ الْأَزْدِيُّ ثنا مُعَاوِيَةُ بْنُ عَمْرٍو ثنا زُهَيْرٌ ثنا أَبُو إِسْحَاقَ عَنْ أَبِي الْأَحْوَصِ عَنْ عَبْدِ اللهِ قَالَ

«مَنْ أَدْرَكَ الْخُطْبَةَ فَالْجُمُعَةُ رَكْعَتَانِ وَمَنْ لَمْ يُدْرِكْهَا فَلْيُصَلِّ أَرْبَعًا وَمَنْ لَمْ يُدْرِكِ الرَّكْعَةَ فَلَا يَعْتَمِدُ بِالسَّجْدَةِ حَتَّى يُدْرِكَ الرَّكْعَةَ»
