وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ أَدْرَكَ رَكْعَةً مِنَ الصُّبْحِ قَبْلَ أَنْ تَطْلُعَ الشَّمْسُ فَقَدْ أَدْرَكَ الصُّبْحَ. وَمَنْ أَدْرَكَ رَكْعَةً مِنَ الْعَصْرِ قَبْلَ أَنْ تغرب الشَّمْس فقد أدْرك الْعَصْر»
Abu Hurayrah reported God’s Messenger as saying, “If anyone performs a raka of the Morning Prayer before sunrise, he has observed the Morning Prayer; and if anyone performs a raka of the afternoon prayer before sunset, he has observed the afternoon prayer.”
