Messenger of Allah ﷺ said, "Whoever could get one rakʿa of a prayer, (in its proper time) he has got the prayer."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ أَدْرَكَ رَكْعَةً مِنَ الصَّلاَةِ فَقَدْ أَدْرَكَ الصَّلاَةَ  

He who finds a rak'ah of the prayer, he in fact finds the prayer.  

أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ أَدْرَكَ رَكْعَةً مِنَ الصَّلاَةِ فَقَدْ أَدْرَكَ الصَّلاَةَ  

If anyone obtains a rak'ah in the prayer (along with the imam), he has obtained the whole prayer.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَدْرَكَ رَكْعَةً مِنَ الصَّلاَةِ فَقَدْ أَدْرَكَ الصَّلاَةَ  

If anyone obtains a rak'ah in the prayer (along with the imam), he has obtained the whole prayer. (Using translation from Abū Dāʾūd 1121)   

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ أَدْرَكَ رَكْعَةً مِنَ الصَّلَاةِ فَقَدْ أَدْرَكَ الصَّلَاةَ  

[Machine] "Whoever catches a unit of prayer has caught the whole prayer."  

«مَنْ أَدْرَكَ الرَّكْعَةَ فَقَدْ أَدْرَكَ الصَّلَاةَ»  

[Machine] He informed him about Ali and Ibn Mas'ud, who said, "Whoever does not catch up with the Rak'ah, should not count it as a Sajdah."  

أَخْبَرَهُ عَنْ عَلِيٍّ وَابْنِ مَسْعُودٍ قَالَا «مَنْ لَمْ يُدْرِكِ الرَّكْعَةَ فَلَا يَعْتَدُّ بِالسَّجْدَةِ»  

If anyone obtains a rak'ah in the prayer (along with the imam), he has obtained the whole prayer. (Using translation from Abū Dāʾūd 1121)  

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ أَدْرَكَ رَكْعَةً مِنَ الصَّلَاةِ فَقَدْ أَدْرَكَ الصَّلَاةَ كُلَّهَا»
