"The people of the Jahiliyyah had two days each year when they would play. When the Messenger of Allah ﷺ came to Al-Madinah he said: 'You had two days when you would play, but Allah (SWT) has given Muslims something instead that is better than them: the day of Al-Fitr and the day of Al-Adha.'" (Using translation from Nasāʾī 1556)
كَانَ لِأَهْلِ الْجَاهِلِيَّةِ يَوْمَانِ مِنْ كُلِّ سَنَةٍ يَلْعَبُونَ فِيهِمَا فَلَمَّا قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ قَالَ كَانَ لَكُمْ يَوْمَانِ تَلْعَبُونَ فِيهِمَا وَقَدْ أَبْدَلَكُمُ اللهُ بِهِمَا خَيْرًا مِنْهُمَا يَوْمُ الْفِطْرِ وَيَوْمُ النَّحْرِ
