[Machine] I was with Muawiyah after the Dhuhr prayer and saw people praying two extra units of prayer after it. He said, "What is this prayer? We prayed with the Messenger of Allah ﷺ and we did not see anyone praying it."  

الطبراني:١٦٨٧١حَدَّثَنَا عَبْدُ اللهِ بْنُ أَحْمَدَ بْنِ حَنْبَلٍ ثنا زَكَرِيَّا بْنُ يَحْيَى زَحْمَوَيْهِ ثنا صَالِحُ بْنُ عُمَرَ عَنْ حَنْظَلَةَ السَّدُوسِيِّ عَنْ عَبْدِ اللهِ بْنِ الْحَارِثِ وَكَانَ مُعَاوِيَةُ خَالَهُ قَالَ

كُنْتُ عِنْدَ مُعَاوِيَةَ بَعْدَ صَلَاةِ الْعَصْرِ فَأَبْصَرَ نَاسًا يُصَلُّونَ بَعْدَهَا رَكْعَتَيْنِ فَقَالَ «مَا هَذِهِ الصَّلَاةُ؟ قَدْ صَلَّيْنَا مَعَ رَسُولِ اللهِ ﷺ فَمَا رَأَيْنَا أَحَدًا يُصَلِّيهَا»
