Mishkat al-Masabih #978

Ibn ‘Umar reported God’s Messenger as saying, “None of you must choose for himself and pray at the rising or setting of the sun.” In a version he said, “When the rim of the sun rises leave off prayer till it comes right up, when the rim of the sun goes below the horizon leave off prayer till it has set, and do not make the rising or setting of the sun your time of prayer, for it rises between the horns of the devil.” (Bukhari and Muslim.)
