Arabic (Original)
وَسَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ لَا صِيَامَ فِي يَوْمَيْنِ يَوْمِ الْأَضْحَى وَيَوْمِ الْفِطْرِ مِنْ رَمَضَانَ.
English Translation
And I heard the Messenger of Allah, peace and blessings be upon him, say, "There is no fasting on two days: the Day of Sacrifice, and the Day of Breaking the Fast at the end of Ramadan."
