darimi:1485Muḥammad b. Aḥmad b. Abū Khalaf > Sufyān b. ʿUyaynah > ʿAmr > al-Zuhrī > Sālim from his father

Salim narrated on the authority of his father that the Messenger of Allah ﷺ used to observe two rak'ahs after Jumu'a. (Using translation from Muslim 882c)  

الدارمي:١٤٨٥أَخْبَرَنَا مُحَمَّدُ بْنُ أَحْمَدَ بْنِ أَبِي خَلَفٍ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ عَمْرٍو عَنِ الزُّهْرِيِّ عَنْ سَالِمٍ عَنْ أَبِيهِ

أَنَّ النَّبِيَّ ﷺ «كَانَ يُصَلِّي بَعْدَ الْجُمُعَةِ رَكْعَتَيْنِ» وأخْبرتْهُ حفْصةُ أنَّهُ كانَ «يُصلِّي إِذَا أَضَاءَ الصُّبْحُ رَكْعَتَيْنِ»
