عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي بَكْرَةٍ عَنْ أَبِيهِ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((شَهْرَانِ لَا يَنْقُصَانِ، فِي كُلِّ وَاحِدٍ مِنْهُمَا عِيدٌ، رَمَضَانُ وَذُو الْحِجَّةِ))
It is narrated from Sayyiduna Abu Bakrah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Two months are never incomplete, each of them contains an Eid; they are Ramadan and Dhul-Hijjah.
