حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ عَبْدِ اللَّهِ الصُّنَابِحِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ إِنَّ الشَّمْسَ تَطْلُعُ وَمَعَهَا قَرْنُ الشَّيْطَانِ فَإِذَا ارْتَفَعَتْ فَارَقَهَا ثُمَّ إِذَا اسْتَوَتْ قَارَنَهَا فَإِذَا زَالَتْ فَارَقَهَا فَإِذَا دَنَتْ لِلْغُرُوبِ قَارَنَهَا فَإِذَا غَرَبَتْ فَارَقَهَا ‏"‏ ‏.‏ وَنَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ الصَّلاَةِ فِي تِلْكَ السَّاعَاتِ ‏.‏

Yahya related to me from Malik from Zayd ibn Aslam from Ata ibnYasar from Abdullah as-Sunabihi that the Messenger of Allah, may Allahbless him and grant him peace, said, "The sun rises and with it is ahorn of Shaytan and when the sun gets higher the horn leaves it. Thenwhen the sun reaches the meridian the horn joins it and when the sundeclines the horn leaves it, and when the sun has nearly set it joinsit again." The Messenger of Allah, may Allah bless him and grant himpeace, forbade prayer at these times. Translation Not Available
