Sunan Abi Dawud, Hadith 1130 ⓘ

Narrated Anas ibn Malik: When the Messenger of Allah 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 said: Allah has substituted for them something better than them, the day of sacrifice and the day of the breaking of the fast.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا حَمَّادٌ، عَنْ حُمَيْدٍ، عَنْ أَنَسٍ، قَالَ قَدِمَ رَسُولُ اللَّهِ صلى الله عليه وسلم الْمَدِينَةَ وَلَهُمْ يَوْمَانِ يَلْعَبُونَ فِيهِمَا فَقَالَ ‏"‏ مَا هَذَانِ الْيَوْمَانِ ‏"‏ ‏.‏ قَالُوا كُنَّا نَلْعَبُ فِيهِمَا فِي الْجَاهِلِيَّةِ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنَّ اللَّهَ قَدْ أَبْدَلَكُمْ بِهِمَا خَيْرًا مِنْهُمَا يَوْمَ الأَضْحَى وَيَوْمَ الْفِطْرِ ‏"‏ ‏.‏
