[Machine] A man came to the Prophet ﷺ and mentioned a hadith, saying, "If you pray Fajr, then delay the (optional) prayer until the sun rises between the horns of Satan, then the prayer is witnessed but invalidated and accepted until the middle of the day."  

البيهقي:٦١٥١وَقَدْ أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ ثنا أَبُو بَكْرِ بْنُ إِسْحَاقَ أنبأ يُوسُفُ بْنُ يَعْقُوبَ ثنا أَحْمَدُ بْنُ عِيسَى ثنا ابْنُ وَهْبٍ عَنْ عِيَاضِ بْنِ عَبْدِ اللهِ الْفِهْرِيِّ عَنْ سَعِيدِ بْنِ أَبِي سَعِيدٍ عَنْ أَبِي هُرَيْرَةَ
