Prayer (Kitab Al-Salat)
2/248. Chapter:
One Who Catches One Rak'ah Of The Friday Prayer
Sunan Abi Dawud
حَدَّثَنَا الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ أَدْرَكَ رَكْعَةً مِنَ الصَّلاَةِ فَقَدْ أَدْرَكَ الصَّلاَةَ " .
Abu Hurairah reported the Messenger of Allah (ﷺ) as saying: If anyone obtains a rak'ah in the prayer (along with the imam), he has obtained the whole prayer.
