مُوَطَّأُ مَالِكٍ
Muwatta Malik 436
The Two 'Ids
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّهُ كَانَ يَأْكُلُ يَوْمَ عِيدِ الْفِطْرِ قَبْلَ أَنْ يَغْدُوَ .
Yahya related to me from Malik from Hisham ibn Urwa from his father that he used to eat on the day of the id al-Fitr before going out.
