From Sahih Bukhari (Hadith 1991):
Narrated Abu Sa`id:The Prophet (ﷺ) forbade the fasting of `Id-ul-Fitr and `Id-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 `Asr (afternoon) prayers
