The Prophet ﷺ forbade the fasting of ʿId-ul-Fitr and ʿId-ul-Adha (two feast days) and also the wearing of As-Samma' (a single garment covering the whole body), and sitting with one's leg drawn up while being wrapped in one garment. He also forbade the prayers after the Fajr (morning) and the ʿAsr (afternoon) prayers.  

نَهَى النَّبِيُّ ﷺ عَنْ صَوْمِ يَوْمِ الْفِطْرِ وَالنَّحْرِ وَعَنِ الصَّمَّاءِ وَأَنْ يَحْتَبِيَ الرَّجُلُ فِي ثَوْبٍ وَاحِدٍ وَعَنْ صَلاَةٍ بَعْدَ الصُّبْحِ وَالْعَصْرِ  

The Messenger of Allah ﷺ forbade fasting on two days, al-Fitr (breaking the fast of Ramadan) and al-Adha (the day of sacrifice), and wearing a tight single garment the raising of which discloses private parts, and sitting with one's legs drawn up and wrapped in one's garment, and forbade praying at two hours, after the Fajr prayer and after the Asr prayer.  

نَهَى رَسُولُ اللَّهِ ﷺ عَنْ صِيَامِ يَوْمَيْنِ يَوْمِ الْفِطْرِ وَيَوْمِ الأَضْحَى وَعَنْ لِبْسَتَيْنِ الصَّمَّاءِ وَأَنْ يَحْتَبِيَ الرَّجُلُ فِي الثَّوْبِ الْوَاحِدِ وَعَنِ الصَّلاَةِ فِي سَاعَتَيْنِ بَعْدَ الصُّبْحِ وَبَعْدَ الْعَصْرِ  

[Machine] The Prophet ﷺ prohibited fasting on the days of Eid al-Fitr and Eid al-Adha, wearing two garments made of silk, a man wearing one garment under another, praying during two specific times after sunrise and after the afternoon prayer.  

نَهَى رَسُولُ اللهِ ﷺ عَنْ صِيَامِ يَوْمَيْنِ يَوْمِ الْفِطْرِ وَيَوْمِ الْأَضْحَى وَعَنْ لِبْسَتَيْنِ الصَّمَّاءِ وَأَنْ يَحْتَبِيَ الرَّجُلُ فِي الثَّوْبِ الْوَاحِدِ وَعَنِ الصَّلَاةِ فِي سَاعَتَيْنِ بَعْدَ الصُّبْحِ وَبَعْدَ الْعَصْرِ
