It was narrated from Ibn Al-Munkadir and Ibrahim bin Maisarah, that they heard Anas say:

"I prayed Zuhr with the Prophet ﷺ in Al-Madinah, four Rak'ahs and 'Asr in Dhul-Hulaifah, two Rak'ahs."

أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ الْمُنْكَدِرِ، وَإِبْرَاهِيمَ بْنِ مَيْسَرَةَ، سَمِعَا أَنَسًا، قَالَ صَلَّيْتُ مَعَ النَّبِيِّ ﷺ الظُّهْرَ بِالْمَدِينَةِ أَرْبَعًا وَبِذِي الْحُلَيْفَةِ الْعَصْرَ رَكْعَتَيْنِ .
