Sunan an-Nasai
أَخْبَرَنِي مُوسَى بْنُ سُلَيْمَانَ بْنِ إِسْمَاعِيلَ بْنِ الْقَاسِمِ، قَالَ حَدَّثَنَا بَقِيَّةُ، عَنْ يُونُسَ، قَالَ حَدَّثَنِي الزُّهْرِيُّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " مَنْ أَدْرَكَ رَكْعَةً مِنَ الْجُمُعَةِ أَوْ غَيْرِهَا فَقَدْ تَمَّتْ صَلاَتُهُ " .
It was narrated from Salim, from his father, that the Prophet (ﷺ) said: "Whoever catches up with with a Rak'ah of Jumu'ah or any other (prayer), his prayer is complete."
