So and so, have you prayed (two rak'ahs)? He said: No. He (the Holy Prophet) said: Then stand and pray.  

بَيْنَا النَّبِيُّ ﷺ يَخْطُبُ يَوْمَ الْجُمُعَةِ إِذْ جَاءَ رَجُلٌ فَقَالَ لَهُ النَّبِيُّ ﷺ أَصَلَّيْتَ يَا فُلاَنُ قَالَ لاَ قَالَ قُمْ فَارْكَعْ  

This hadith is narrated by Jabir through another chain of transmitters but Hammad (one of the narrators) made no mention of the two rak'ahs.  

عَنِ النَّبِيِّ ﷺ كَمَا قَالَ حَمَّادٌ وَلَمْ يَذْكُرِ الرَّكْعَتَيْنِ  

Have you observed prayer? He said: No. He (the Holy Prophet) said: Stand and offer the two rak'ahs. According to Qutaiba, the words are:" He said: Offer two rak'ahs."  

سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ يَقُولُ دَخَلَ رَجُلٌ الْمَسْجِدَ وَرَسُولُ اللَّهِ ﷺ يَخْطُبُ يَوْمَ الْجُمُعَةِ فَقَالَ أَصَلَّيْتَ قَالَ لاَ قَالَ قُمْ فَصَلِّ الرَّكْعَتَيْنِ وَفِي رِوَايَةِ قُتَيْبَةَ قَالَ صَلِّ رَكْعَتَيْنِ  

Have you offered two rak'ahs? He said: No. Upon this he said: Then observe (them).  

أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ يَقُولُ جَاءَ رَجُلٌ وَالنَّبِيُّ ﷺ عَلَى الْمِنْبَرِ يَوْمَ الْجُمُعَةِ يَخْطُبُ فَقَالَ لَهُ أَرَكَعْتَ رَكْعَتَيْنِ قَالَ لاَ فَقَالَ «ارْكَعْ»  

When any one of you comes for the Friday (prayer) and the Imam comes out (from his apartment), (even then) should observe two rak'ahs (of prayer).  

أَنَّ النَّبِيَّ ﷺ خَطَبَ فَقَالَ إِذَا جَاءَ أَحَدُكُمْ يَوْمَ الْجُمُعَةِ وَقَدْ خَرَجَ الإِمَامُ فَلْيُصَلِّ رَكْعَتَيْنِ  

Have you observed two rak'ahs? He said: No. He (the Holy Prophet) said: Stand and observe them  

أَنَّهُ قَالَ جَاءَ سُلَيْكٌ الْغَطَفَانِيُّ يَوْمَ الْجُمُعَةِ وَرَسُولُ اللَّهِ ﷺ قَاعِدٌ عَلَى الْمِنْبَرِ فَقَعَدَ سُلَيْكٌ قَبْلَ أَنْ يُصَلِّيَ فَقَالَ لَهُ النَّبِيُّ ﷺ أَرَكَعْتَ رَكْعَتَيْنِ قَالَ لاَ قَالَ قُمْ فَارْكَعْهُمَا  

Sulaik Ghatafani came on Friday when the Messenger of Allah ﷺ was delivering the sermon. He (Sulaik) sat down. He (the Holy Prophet) said to him: 0 Sulaik I stand and observe two rak'ahs and make them short, and then said: When any one of you comes on Friday, while the Imam delivers the sermon, he should observe two rak'ahs and should make them short.  

جَاءَ سُلَيْكٌ الْغَطَفَانِيُّ يَوْمَ الْجُمُعَةِ وَرَسُولُ اللَّهِ ﷺ يَخْطُبُ فَجَلَسَ فَقَالَ لَهُ يَا سُلَيْكُ قُمْ فَارْكَعْ رَكْعَتَيْنِ وَتَجَوَّزْ فِيهِمَا ثُمَّ قَالَ إِذَا جَاءَ أَحَدُكُمْ يَوْمَ الْجُمُعَةِ وَالإِمَامُ يَخْطُبُ فَلْيَرْكَعْ رَكْعَتَيْنِ وَلْيَتَجَوَّزْ فِيهِمَا
