Narrator:Ali
الْمُغِيرَةِ، قَالَ حَدَّثَنَا عَمْرُو بْنُ أَبِي قَيْسٍ، عَنْ شُعَيْبِ بْنِ خَالِدٍ، عَنْ أَبِي إِسْحَاقَ، قَالَ قَالَ عَلِيٌّ - رضى الله عنه - وَنَظَرَ إِلَى ابْنِهِ الْحَسَنِ فَقَالَ إِنَّ ابْنِي هَذَا سَيِّدٌ كَمَا سَمَّاهُ النَّبِيُّ صلى الله عليه وسلم وَسَيَخْرُجُ مِنْ صُلْبِهِ رَجُلٌ يُسَمَّى بِاسْمِ نَبِيِّكُمْ يُشْبِهُهُ فِي الْخُلُقِ وَلاَ يُشْبِهُهُ فِي الْخَلْقِ ثُمَّ ذَكَرَ قِصَّةَ يَمْلأُ الأَرْضَ عَدْلاً .
Abu Dawud said:
Abu Ishaq told that Ali looked at his son al-Hasan and said: This son of mine is a sayyid (chief) as named by the Prophet (ﷺ), and from his loins will come forth a man who will be called by the name of your Prophet (ﷺ) and resemble him in conduct but not in appearance. He then mentioned the story about his filling the earth with justice.
Reported by Abu Dawud (No. 4290).
