Ibn 'Umar saw a man praying two rak'ahs after the Friday prayer on the same place (where he offered the Friday prayer). He pushed him and said: Do you offer four rak'ahs of Friday prayer ? 'Abd Allah (b. 'Umar) used to pray two rak'ahs in his house after the Friday prayer, and he used to say: This is how the Messenger of Allah ﷺ did.  

وَقَالَ أَتُصَلِّي الْجُمُعَةَ أَرْبَعًا وَكَانَ عَبْدُ اللَّهِ يُصَلِّي يَوْمَ الْجُمُعَةِ رَكْعَتَيْنِ فِي بَيْتِهِ وَيَقُولُ هَكَذَا فَعَلَ رَسُولُ اللَّهِ ﷺ  

Nafi' said: Ibn Umar used to lengthen his prayer before the Friday prayer and would offer two rak'ahs after it in his house. He used to say that the Messenger of Allah ﷺ would do that.  

أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَفْعَلُ ذَلِكَ  

I offered the Friday prayer along with him in enclosure. When I uttered the salutation I stood up in my place and prayed. When he went in, he sent me a message saying: Never again do what you have done. When you pray the Friday prayer, you must not join another prayer to it till you have engaged in conversation or gone out, for the Prophet of Allah ﷺ gave the precise command not to join on prayer till you have engaged in conversation or gone out.  

عَنْ شَىْءٍ رَأَى مِنْهُ مُعَاوِيَةُ فِي الصَّلاَةِ فَقَالَ صَلَّيْتُ مَعَهُ الْجُمُعَةَ فِي الْمَقْصُورَةِ فَلَمَّا سَلَّمْتُ قُمْتُ فِي مَقَامِي فَصَلَّيْتُ فَلَمَّا دَخَلَ أَرْسَلَ إِلَىَّ فَقَالَ لاَ تَعُدْ لِمَا صَنَعْتَ إِذَا صَلَّيْتَ الْجُمُعَةَ فَلاَ تَصِلْهَا بِصَلاَةٍ حَتَّى تَكَلَّمَ أَوْ تَخْرُجَ فَإِنَّ نَبِيَّ اللَّهِ ﷺ أَمَرَ بِذَلِكَ أَنْ لاَ تُوصَلَ صَلاَةٌ بِصَلاَةٍ حَتَّى يَتَكَلَّمَ أَوْ يَخْرُجَ  

When Ibn 'Umar offered the Friday prayer in Mecca he would go forward and pray two rak'ahs, he would then go forward and pray four rak'ahs; but when he was in Medina, he offered the Friday prayer, then returned to his house and prayed two rak'ahs, not praying them in the mosque. Someone mentioned this to him and he replied that the Messenger of Allah ﷺ used to do it.  

كَانَ إِذَا كَانَ بِمَكَّةَ فَصَلَّى الْجُمُعَةَ تَقَدَّمَ فَصَلَّى رَكْعَتَيْنِ ثُمَّ تَقَدَّمَ فَصَلَّى أَرْبَعًا وَإِذَا كَانَ بِالْمَدِينَةِ صَلَّى الْجُمُعَةَ ثُمَّ رَجَعَ إِلَى بَيْتِهِ فَصَلَّى رَكْعَتَيْنِ وَلَمْ يُصَلِّ فِي الْمَسْجِدِ فَقِيلَ لَهُ فَقَالَ كَانَ رَسُولُ اللَّهِ ﷺ يَفْعَلُ ذَلِكَ  

If anyone of you prays after the Friday prayer, he should say for rak'ahs. According to the version of the narrator Ibn Yunus, the tradition goes: When you have offered the Friday prayer, pray after it four rak'ahs. He said: My father said to me: My son, if you have said two rak'ahs in the mosque, then you comes to your house, pray two rak'ahs more.  

قَالَ رَسُولُ اللَّهِ ﷺ قَالَ ابْنُ الصَّبَّاحِ قَالَ مَنْ كَانَ مُصَلِّيًا بَعْدَ الْجُمُعَةِ فَلْيُصَلِّ أَرْبَعًا وَتَمَّ حَدِيثُهُ وَقَالَ ابْنُ يُونُسَ إِذَا صَلَّيْتُمُ الْجُمُعَةَ فَصَلُّوا بَعْدَهَا أَرْبَعًا قَالَ فَقَالَ لِي أَبِي يَا بُنَىَّ فَإِنْ صَلَّيْتَ فِي الْمَسْجِدِ رَكْعَتَيْنِ ثُمَّ أَتَيْتَ الْمَنْزِلَ أَوِ الْبَيْتَ فَصَلِّ رَكْعَتَيْنِ  

The Messenger of Allah ﷺ used to pray two rak'ahs in his house after the Friday prayer. Abu Dawud said: This tradition has been transmitted in a similar way by 'Abd Allah b. Dinar from Ibn 'Umar.  

كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّي بَعْدَ الْجُمُعَةِ رَكْعَتَيْنِ فِي بَيْتِهِ  

Ibn Jurayj said: Ata' told me that he saw Ibn Umar pray after the Friday prayer. He moved a little from the place where he offered the Friday prayer. Then he would pray two rak'ahs. He then walked far away from that place and would offer four rak'ahs. I asked Ata': How many times did you see Ibn Umar do that? He replied: Many times. AbuDawud said: This has been narrated by AbdulMalik ibn AbuSulayman, but did not narrate it completely.  

عَنْ مُصَلاَّهُ الَّذِي صَلَّى فِيهِ الْجُمُعَةَ قَلِيلاً غَيْرَ كَثِيرٍ قَالَ فَيَرْكَعُ رَكْعَتَيْنِ قَالَ ثُمَّ يَمْشِي أَنْفَسَ مِنْ ذَلِكَ فَيَرْكَعُ أَرْبَعَ رَكَعَاتٍ قُلْتُ لِعَطَاءٍ كَمْ رَأَيْتَ ابْنَ عُمَرَ يَصْنَعُ ذَلِكَ قَالَ مِرَارًا
