[Machine] On the authority of the Prophet ﷺ , he said: "When one of you prays a unit of the Fajr prayer and the sun rises, then let him pray another unit towards it."
عَنِ النَّبِيِّ ﷺ قَالَ إِذَا صَلَّى أَحَدُكُمْ رَكْعَةً مِنْ صَلَاةِ الصُّبْحِ ثُمَّ طَلَعَتِ الشَّمْسُ فَلْيُصَلِّ إِلَيْهَا أُخْرَى
