Arabic (Original)
حَدَّثَنَا أَبُو أَحْمَدَ الزُّبَيْرِيُّ حَدَّثَنَا سُفْيَانُ عَنْ أَبِي إِسْحَاقَ عَنْ مُجَاهِدٍ عَنِ ابْنِ عُمَرَ قَالَ رَمَقْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ شَهْرًا فَكَانَ يَقْرَأُ فِي الرَّكْعَتَيْنِ قَبْلَ الْفَجْرِ قُلْ يَا أَيُّهَا الْكَافِرُونَ وَقُلْ هُوَ اللَّهُ أَحَدٌ.
English Translation
Abu Ahmad al-Zubayri told us: Sufyan told us, from Abu Ishaq, from Mujahid, from Ibn 'Umar, who said: I watched the Prophet, peace and blessings be upon him, for a month, and he used to recite in the two rak'ahs before dawn: "Say, O disbelievers" and "Say, He is Allah, the One."
