Compiled by Imam Abu Dawud as-Sijistani
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 " .
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.
