عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ: ((إِنَّ يَوْمَ الْجُمُعَةِ يَوْمُ عِيدٍ، فَلَا تَجْعَلُوا يَوْمَ عِيدِكُمْ يَوْمَ صِيَامِكُمْ إِلَّا أَنْ تَصُومُوا قَبْلَهُ أَوْ بَعْدَهُ))
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Verily, Friday is a day of Eid, so do not fast on this day of Eid, except that you fast a day before it or a day after it.
