ذِكْرُ الْبَيَانِ بِأَنَّ الْعَرَبَ تُطْلِقُ فِي لُغَتِهَا اسْمَ الرَّكْعَةِ عَلَى السَّجْدَةِ
The Messenger of Allah said: "Whoever catches one Rak'ah of the 'Asr before the sun sets, then he has caught it, and whoever catches one Rak'ah of the Subh before the sun rises, then he has caught it." (Using translation from Ibn Mājah 699)
قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ أَدْرَكَ مِنَ الْعَصْرِ سَجْدَةً قَبْلَ أَنٌ تَغْرُبَ الشَّمْسُ أَوْ مِنَ الصُّبْحِ قَبْلَ أَنْ تَطْلُعَ الشَّمْسُ فَقَدْ أَدْرَكَهَا»
