"The Messenger of Allah ﷺ said: 'When the edge of the sun rises, then delay prayer until it has fully risen, and when the edge of the sun starts to set, delay prayer until it has fully set.'" (Using translation from Nasāʾī 571)
قَالَ رَسُولُ اللهِ ﷺ «إِذَا طَلَعَ حَاجِبُ الشَّمْسِ فَأَخِّرُوا الصَّلَاةَ حَتَّى تَشْرُقَ فَإِذَا غَابَ حَاجِبُ الشَّمْسِ فَأَخِّرُوا الصَّلَاةَ حَتَّى تَغْرُبَ»
