When any one of you observes the Jumu'a prayer (two obligatory rak'ahs in congregation), he should observe four (rak'ahs) afterwards.  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا صَلَّى أَحَدُكُمُ الْجُمُعَةَ فَلْيُصَلِّ بَعْدَهَا أَرْبَعًا  

When you observe prayer after (the two obligatory rak'ahs) of Jumu'ah, you should observe four rak'ahs (and 'Amr in his narration has made this addition that Ibn Idris said this on the authority of Suhail): And if you are in a hurry on account of something, you should observe two rak'ahs in the mosque and two when you return (to your house).  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا صَلَّيْتُمْ بَعْدَ الْجُمُعَةِ فَصَلُّوا أَرْبَعًا زَادَ عَمْرٌو فِي رِوَايَتِهِ قَالَ ابْنُ إِدْرِيسَ قَالَ سُهَيْلٌ فَإِنْ عَجِلَ بِكَ شَىْءٌ فَصَلِّ رَكْعَتَيْنِ فِي الْمَسْجِدِ وَرَكْعَتَيْنِ إِذَا رَجَعْتَ  

When any one amongst you observes prayer after Jumu'a, he should observe four rak'ahs. (In the hadith transmitted by Jarir the word minkum is not recorded.)  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ كَانَ مِنْكُمْ مُصَلِّيًا بَعْدَ الْجُمُعَةِ فَلْيُصَلِّ أَرْبَعًا وَلَيْسَ فِي حَدِيثِ جَرِيرٍ مِنْكُمْ  

The Messenger of Allah (may peace be updn him) used to do this.  

أَنَّهُ كَانَ إِذَا صَلَّى الْجُمُعَةَ انْصَرَفَ فَسَجَدَ سَجْدَتَيْنِ فِي بَيْتِهِ ثُمَّ قَالَ كَانَ رَسُولُ اللَّهِ ﷺ يَصْنَعُ ذَلِكَ  

He did not observe (Nafl) prayer after Jumu'a till he went back and observed two rak'ahs in his house. Yahya said: I guess that I uttered these words (before Imam Malik) that he of course observed (them).  

أَنَّهُ وَصَفَ تَطَوُّعَ صَلاَةِ رَسُولِ اللَّهِ ﷺ قَالَ فَكَانَ لاَ يُصَلِّي بَعْدَ الْجُمُعَةِ حَتَّى يَنْصَرِفَ فَيُصَلِّي رَكْعَتَيْنِ فِي بَيْتِهِ قَالَ يَحْيَى أَظُنُّنِي قَرَأْتُ فَيُصَلِّي أَوْ أَلْبَتَّةَ  

Salim narrated on the authority of his father that the Messenger of Allah ﷺ used to observe two rak'ahs after Jumu'a.  

أَنَّ النَّبِيَّ ﷺ كَانَ يُصَلِّي بَعْدَ الْجُمُعَةِ رَكْعَتَيْنِ  

Yes, I observed the Jumuʿa prayer along with him in Maqsura and when the Imam pronounced salutation I stood up at my place and observed (Sunan rakʿahs). As he entered (the apartment) he sent for me and said: Do not repeat what you have done. Whenever you have observed the Jumuʿa prayer, do not observe (Sunan prayer) till you, have talked or gone out, for the Messenger of Allah ﷺ had ordered us to do this and not to combine two (types of) prayers without talking or going out.  

عَنْ شَىْءٍ رَآهُ مِنْهُ مُعَاوِيَةُ فِي الصَّلاَةِ فَقَالَ نَعَمْ صَلَّيْتُ مَعَهُ الْجُمُعَةَ فِي الْمَقْصُورَةِ فَلَمَّا سَلَّمَ الإِمَامُ قُمْتُ فِي مَقَامِي فَصَلَّيْتُ فَلَمَّا دَخَلَ أَرْسَلَ إِلَىَّ فَقَالَ لاَ تَعُدْ لِمَا فَعَلْتَ إِذَا صَلَّيْتَ الْجُمُعَةَ فَلاَ تَصِلْهَا بِصَلاَةٍ حَتَّى تَكَلَّمَ أَوْ تَخْرُجَ فَإِنَّ رَسُولَ اللَّهِ ﷺ أَمَرَنَا بِذَلِكَ أَنْ لاَ تُوصَلَ صَلاَةٌ حَتَّى نَتَكَلَّمَ أَوْ نَخْرُجَ  

When he (the Imam) pronounced salutation I stood up at my place. No mention was made of the Imam in it.  

أَنَّهُ قَالَ فَلَمَّا سَلَّمَ قُمْتُ فِي مَقَامِي وَلَمْ يَذْكُرِ الإِمَامَ
