[Machine] The Messenger of Allah ﷺ said, "When one of you comes to Jumu'ah prayer and the Imam is delivering the sermon, let him pray two light rak'ahs."  

قَالَ رَسُولُ اللهِ ﷺ إِذَا جَاءَ أَحَدُكُمْ إِلَى الْجُمُعَةِ وَالْإِمَامُ يَخْطُبُ فَلْيُصَلِّ رَكْعَتَيْنِ خَفِيفَتَيْنِ  

[Machine] Salik Al-Ghatafani came while the Prophet ﷺ was delivering a sermon, so the Prophet ﷺ ordered him to pray two units of prayer in which he would perform acts of tashahhud. He said, "When any of you comes while the imam is delivering the sermon, let him pray two units of prayer in which he would perform acts of tashahhud."  

جَاءَ سُلَيْكٌ الْغَطَفَانِيُّ وَالنَّبِيُّ ﷺ يَخْطُبُ فَأَمَرَهُ النَّبِيُّ ﷺ أَنْ يُصَلِّيَ رَكْعَتَيْنِ يَتَجَوَّزُ فِيهِمَا وَقَالَ «إِذَا جَاءَ أَحَدُكُمْ وَالْإِمَامُ يَخْطُبُ فَلْيُصَلِّ رَكْعَتَيْنِ يَتَجَوَّزُ فِيهِمَا»  

"إذَا جاءَ أحدُكم يومَ الجُمعةِ والإِمامُ يخطُب فليُصَلِّ ركْعَتين، ولْيَتَجَوَّزْ فيهما" .  

"يَا نُعْمَانُ! صَلِّ رَكعَتَيْنِ تَجَوَّزْ فيهِمَا، وإِذَا جَاءَ أَحَدُكُمْ وَالإِمَامُ يَخْطُبُ فَليُصَلّ رَكْعَتَينِ وَلْيُخَفِّفْهُمَا".
