(10) باب مَنْ رَخَّصَ فِيهِمَا إِذَا كَانَتِ الشَّمْسُ مُرْتَفِعَةً
Narrated Abdullah ibn Abbas:
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.
