[Machine] The Messenger of Allah ﷺ said, "Whoever catches a rak'ah (unit of prayer) of the Friday prayer, let him pray another one." It has also been narrated from Salih bin Abi Al-Akhdar from Az-Zuhri.
أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ أَدْرَكَ مِنَ الْجُمُعَةِ رَكْعَةً فَلْيُصَلِّ إِلَيْهَا أُخْرَى وَكَذَلِكَ رُوِيَ عَنْ صَالِحِ بْنِ أَبِي الْأَخْضَرِ عَنِ الزُّهْرِيِّ
