It was narrated that Anas bin Malik said:

"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 (Subhanahu-wa-Taala) has given Muslims something instead that is better than them: the day of Al-Fitr and the day of Al-Adha.'"

أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ أَنْبَأَنَا إِسْمَاعِيلُ، قَالَ حَدَّثَنَا حُمَيْدٌ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كَانَ لأَهْلِ الْجَاهِلِيَّةِ يَوْمَانِ فِي كُلِّ سَنَةٍ يَلْعَبُونَ فِيهِمَا فَلَمَّا قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ قَالَ " كَانَ لَكُمْ يَوْمَانِ تَلْعَبُونَ فِيهِمَا وَقَدْ أَبْدَلَكُمُ اللَّهُ بِهِمَا خَيْرًا مِنْهُمَا يَوْمَ الْفِطْرِ وَيَوْمَ الأَضْحَى " .
