The sun and the shaytan's horn in the prayer times

Al-Muwatta relates from Zayd ibn Aslam from Ata ibn Yasar from Abdullah al-Sunabihi that the Prophet ﷺ reported the sun rises with the shaytan's horn: when it climbs he parts from it, when it stands he joins it, when it declines he parts, when it nears sunset he joins it, when it sets he parts — and he forbade prayer in those hours ¹ Muwatta 584.

This hadith is among the foundations of the prohibition of prayer in disliked times; the shaytan's horn accompanies the sun in certain hours ¹.
