وَعَن أبي إِسحاق قَالَ: قَالَ عَلِيٌّ وَنَظَرَ إِلَى ابْنِهِ الْحَسَنِ قَالَ: إِنَّ ابْنِي هَذَا سَيِّدٌ كَمَا سَمَّاهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَسَيَخْرُجُ مِنْ صُلْبِهِ رَجُلٌ يُسَمَّى بِاسْمِ نَبِيِّكُمْ يُشْبِهُهُ فِي الْخَلْقِ - ثُمَّ ذَكَرَ قِصَّةَ - يَمْلَأُ الْأَرْضَ عَدْلًا. رَوَاهُ أَبُو دَاوُدَ وَلَمْ يَذْكُرِ الْقِصَّةَ
Abu Ishaq told that `Ali looked at his son al-Hasan and said, "This son of mine is a sayyid as God's messenger named him, and from his loins will come forth a man who will be called by your Prophet's name and resemble him in nature but not in appearance." He then mentioned the story about his filling the earth with justice. Abu Dawud transmitted it, but did not mention the story.
