When the Messenger of Allah ﷺ came to Medina, the people had two days on which they engaged in games. He asked: What are these two days (what is the significance)? They said: We used to engage ourselves on them in the pre-Islamic period. The Messenger of Allah ﷺ said: Allah has substituted for them something better than them, the day of sacrifice and the day of the breaking of the fast.
قَدِمَ رَسُولُ اللَّهِ ﷺ الْمَدِينَةَ وَلَهُمْ يَوْمَانِ يَلْعَبُونَ فِيهِمَا فَقَالَ مَا هَذَانِ الْيَوْمَانِ قَالُوا كُنَّا نَلْعَبُ فِيهِمَا فِي الْجَاهِلِيَّةِ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّ اللَّهَ قَدْ أَبْدَلَكُمْ بِهِمَا خَيْرًا مِنْهُمَا يَوْمَ الأَضْحَى وَيَوْمَ الْفِطْرِ
