وَعَنْ أَبِي بَكْرَةَ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «شَهْرَا عِيدٍ لَا يَنْقُصَانِ: رَمَضَانُ وَذُو الْحِجَّةِ»
Abu Bakra reported God’s messenger as saying, “The months of festival, Ramadan and Dhul-hijja, are not defective.”* *The most probable meaning is that, even if these months have only twenty-nine days, they are not on that account to be considered deficient in comparison with a month which has thirty days.
