[Machine] "He (Hasan) used to say that the Prophet ﷺ would go for the Eid al-Adha and Eid al-Fitr prayer when the sun rises high, and that is also transmitted and witnessed by the actions of the Muslims in doing that or something similar to it."  

البيهقي:٦١٥٠وَأَخْبَرَنَا أَبُو سَعِيدِ بْنُ أَبِي عَمْرٍو ثنا أَبُو الْعَبَّاسُ أنبأ الرَّبِيعُ أنبأ الشَّافِعِيُّ أنبأ الثِّقَةُ

أَنَّ الْحَسَنَ كَانَ يَقُولُ إِنَّ النَّبِيَّ ﷺ كَانَ يَغْدُو إِلَى الْأَضْحَى وَالْفِطْرِ حِينَ تَطْلُعُ الشَّمْسُ فَيَتَتَامُ طُلُوعُهَا وَهَذَا أَيْضًا مُرْسَلٌ وَشَاهِدُهُ عَمَلُ الْمُسْلِمِينَ بِذَلِكَ أَوْ بِمَا يَقْرُبُ مِنْهُ مُؤَخَّرًا عَنْهُ
