"Whoever catches up with two Rak'ahs of 'Asr prayer before the sun sets, or one Rak'ah of the Subh prayer before the sun rises, has caught it."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ أَدْرَكَ رَكْعَتَيْنِ مِنْ صَلاَةِ الْعَصْرِ قَبْلَ أَنْ تَغْرُبَ الشَّمْسُ أَوْ رَكْعَةً مِنْ صَلاَةِ الصُّبْحِ قَبْلَ أَنْ تَطْلُعَ الشَّمْسُ فَقَدْ أَدْرَكَ  

"Whoever catches up with one Rak'ah of 'Asr prayer before the sun sets, or catches up with one Rak'ah of Fajr before the sun rises, has caught it."  

عَنِ النَّبِيِّ ﷺ قَالَ مَنْ أَدْرَكَ رَكْعَةً مِنْ صَلاَةِ الْعَصْرِ قَبْلَ أَنْ تَغِيبَ الشَّمْسُ أَوْ أَدْرَكَ رَكْعَةً مِنَ الْفَجْرِ قَبْلَ طُلُوعِ الشَّمْسِ فَقَدْ أَدْرَكَ  

"If any one of you catches the first prostration of 'Asr prayer before the sun sets, let him complete his prayer, and if he catches up with the first prostration of Fajr prayer before the sub rises, let him complete his prayer."  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا أَدْرَكَ أَحَدُكُمْ أَوَّلَ سَجْدَةٍ مِنْ صَلاَةِ الْعَصْرِ قَبْلَ أَنْ تَغْرُبَ الشَّمْسُ فَلْيُتِمَّ صَلاَتَهُ وَإِذَا أَدْرَكَ أَوَّلَ سَجْدَةٍ مِنْ صَلاَةِ الصُّبْحِ قَبْلَ أَنْ تَطْلُعَ الشَّمْسُ فَلْيُتِمَّ صَلاَتَهُ  

"Whoever catches up with a Rak'ah of the Subh prayer before the sun rises, then he has caught up with Subh, and whoever catches up with a Rak'ah of 'Asr prayer before the sun sets, then he has caught up with 'Asr."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ أَدْرَكَ رَكْعَةً مِنْ صَلاَةِ الصُّبْحِ قَبْلَ أَنْ تَطْلُعَ الشَّمْسُ فَقَدْ أَدْرَكَ الصُّبْحَ وَمَنْ أَدْرَكَ رَكْعَةً مِنَ الْعَصْرِ قَبْلَ أَنْ تَغْرُبَ الشَّمْسُ فَقَدْ أَدْرَكَ الْعَصْرَ  

'Are you not going to pray?' He said: 'The Messenger of Allah ﷺ said: 'There is no prayer after 'Asr until the sun has set, nor after Subh until the sun has risen.'"  

إِنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ صَلاَةَ بَعْدَ الْعَصْرِ حَتَّى تَغِيبَ الشَّمْسُ وَلاَ بَعْدَ الصُّبْحِ حَتَّى تَطْلُعَ الشَّمْسُ
