مُوَطَّأُ مَالِكٍ
Muwatta Malik 440
The Two 'Ids
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، لَمْ يَكُنْ يُصَلِّي يَوْمَ الْفِطْرِ قَبْلَ الصَّلاَةِ وَلاَ بَعْدَهَا .
Yahya related to me from Malik from Nafi that Abdullah ibn Umar did not pray either before the prayer or after it on the day of Fitr.
