Sunan Abu Dawud · Hadith 1121
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
