It was narrated from Abu Hurairah that the Prophet ﷺ forbade praying after 'Asr until the sun had set, and after Subh until the sun had risen.  

أَنَّ النَّبِيَّ ﷺ نَهَى عَنِ الصَّلاَةِ بَعْدَ الْعَصْرِ حَتَّى تَغْرُبَ الشَّمْسُ وَعَنِ الصَّلاَةِ بَعْدَ الصُّبْحِ حَتَّى تَطْلُعَ الشَّمْسُ  

"I heard more than one of the Companions of the Prophet ﷺ - including 'Umar who was one of the dearest of them to me - that the Messenger of Allah ﷺ forbade praying after Fajr until the sun had risen, and praying after 'Asr until the sun had set."  

سَمِعْتُ غَيْرَ وَاحِدٍ مِنْ أَصْحَابِ النَّبِيِّ ﷺ مِنْهُمْ عُمَرُ وَكَانَ مِنْ أَحَبِّهِمْ إِلَىَّ أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنِ الصَّلاَةِ بَعْدَ الْفَجْرِ حَتَّى تَطْلُعَ الشَّمْسُ وَعَنِ الصَّلاَةِ بَعْدَ الْعَصْرِ حَتَّى تَغْرُبَ الشَّمْسُ
