Narrated Ibn `Umar:
حَدَّثَنَا مُحَمَّدٌ ، أَخْبَرَنَا عَبْدَةُ ، عَنْ هِشَامِ بْنِ عُرْوَةَ ، عَنْ أَبِيهِ ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا طَلَعَ حَاجِبُ الشَّمْسِ فَدَعُوا الصَّلاَةَ حَتَّى تَبْرُزَ، وَإِذَا غَابَ حَاجِبُ الشَّمْسِ فَدَعُوا الصَّلاَةَ حَتَّى تَغِيبَ ". " وَلاَ تَحَيَّنُوا بِصَلاَتِكُمْ طُلُوعَ الشَّمْسِ وَلاَ غُرُوبَهَا، فَإِنَّهَا تَطْلُعُ بَيْنَ قَرْنَىْ شَيْطَانٍ ". أَوِ الشَّيْطَانِ. لاَ أَدْرِي أَىَّ ذَلِكَ قَالَ هِشَامٌ .
Allah's Messenger (ﷺ) said, "When the (upper) edge of the sun appears (in the morning), don't perform a prayer till the sun appears in full, and when the lower edge of the sun sets, 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).
