Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ قَالَ حَدَّثَنَا يَزِيدُ بْنُ كَيْسَانَ قَالَ حَدَّثَنِي أَبُو حَازِمٍ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ احْشُدُوا فَإِنِّي سَأَقْرَأُ عَلَيْكُمْ ثُلُثَ الْقُرْآنِ قَالَ فَحَشَدَ مَنْ حَشَدَ ثُمَّ خَرَجَ فَقَرَأَ قُلْ هُوَ اللَّهُ أَحَدٌ ثُمَّ دَخَلَ فَقَالَ بَعْضُنَا لِبَعْضٍ هَذَا خَبَرٌ جَاءَهُ مِنْ السَّمَاءِ فَذَلِكَ الَّذِي أَدْخَلَهُ ثُمَّ خَرَجَ فَقَالَ إِنِّي قَدْ قُلْتُ لَكُمْ إِنِّي سَأَقْرَأُ عَلَيْكُمْ ثُلُثَ الْقُرْآنِ وَإِنَّهَا تَعْدِلُ ثُلُثَ الْقُرْآنِ.
English Translation
Yahya ibn Sa'id narrated to us, who said: Yazid ibn Kaysan narrated to us, who said: Abu Hazim narrated to me, from Abu Hurairah, who said: The Messenger of Allah (peace be upon him) said: "Gather together, for I will recite to you a third of the Quran." So those who could gather, gathered. Then he came out and recited 'Say: He is Allah, the One' (Surah al-Ikhlas). Then he went back inside. Some of us said to others: "News must have come to him from the heavens; that is what made him go inside." Then he came out and said: "I told you I would recite to you a third of the Quran, and indeed it (Surah al-Ikhlas) is equal to a third of the Quran."
