Hadith on Festivals: Allah has replaced the celebrations of ignorance with Islam

Anas ibn Malik reported: The Messenger of Allah, peace and blessings be upon him, arrived in Medina during two days in which they were celebrating. The Prophet said, “What are these two days?” They said, “We would celebrate these two days in the time of ignorance.” The Prophet said, “Verily, Allah has replaced these two days with two better days: the day of sacrifices (eid al-adha) and the day of breaking fast (eid al-fitr).”

عَنْ أَنَسٍ قَالَ قَدِمَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْمَدِينَةَ وَلَهُمْ يَوْمَانِ يَلْعَبُونَ فِيهِمَا فَقَالَ مَا هَذَانِ الْيَوْمَانِ قَالُوا كُنَّا نَلْعَبُ فِيهِمَا فِي الْجَاهِلِيَّةِ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ اللَّهَ قَدْ أَبْدَلَكُمْ بِهِمَا خَيْرًا مِنْهُمَا يَوْمَ الْأَضْحَى وَيَوْمَ الْفِطْرِ
