The Book of Prayer
وَعَنْ أَبِي سَعِيدٍ قَالَ: { كَانَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -لَا يُصَلِّي قَبْلَ اَلْعِيدِ شَيْئًا, فَإِذَا رَجَعَ إِلَى مَنْزِلِهِ صَلَّى رَكْعَتَيْنِ } رَوَاهُ اِبْنُ مَاجَهْ بِإِسْنَادٍ حَسَنٍ [1] .
Narrated Abu Sa'id (RA): The Prophet (ﷺ) never used to offer any prayer before the 'Eid prayer. But when he went back home, he used to pray two Rak'at. [Reported by Ibn Majah through a Hasan (good) chain of narrators].
