Some reliable people testified before me, and among them was Umar ibn al-Khattab, and most reliable in my eyes was Umar: The Prophet of Allah ﷺ said: There is no prayer after the dawn prayer until the sun rises; and there is no prayer after the 'Asr prayer until the sun sets.
أَنَّ نَبِيَّ اللَّهِ ﷺ قَالَ لاَ صَلاَةَ بَعْدَ صَلاَةِ الصُّبْحِ حَتَّى تَطْلُعَ الشَّمْسُ وَلاَ صَلاَةَ بَعْدَ صَلاَةِ الْعَصْرِ حَتَّى تَغْرُبَ الشَّمْسُ
