وَلَا تَحَيَّنُوا بِصَلَاتِكُمْ طُلُوعَ الشَّمْسِ وَلَا غُرُوبَهَا فَإِنَّهَا تَطْلُعُ بَيْنَ قَرْنَيْ شَيْطَانٍ أَوِ الشَّيْطَانِ " لَا أَدْرِي أَيَّ ذَلِكَ ، قَالَ هِشَامٌ .
Don't perform a prayer till it sets completely. And you should not seek to pray at sunrise or sunset for the sun rises between two sides of the head of the devil (or Satan).
