"I heard the Messenger of Allah ﷺ say: 'There is no prayer after Fajr until the sun has clearly risen, and no prayer after 'Asr until the sun has fully set.'"
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ صَلاَةَ بَعْدَ الْفَجْرِ حَتَّى تَبْزُغَ الشَّمْسُ وَلاَ صَلاَةَ بَعْدَ الْعَصْرِ حَتَّى تَغْرُبَ الشَّمْسُ
