حدثنا الحسن بن أحمد بن إدريس - رضي الله عنه - قال: حدثنا أبي عن محمد ابن الحسين بن أبي الخطاب، ويعقوب بن يزيد، ومحمد بن أبي الصهبان جميعا، عن محمد بن أبي عمير، عن أبان بن عثمان، عن الصادق جعفر بن محمد، عن أبيه، عن جده عليهم السلام، قال: إن أعرابيا أتى رسول الله صلى الله عليه وآله فخرج إليه في رداء ممشق  ، فقال: يا محمد لقد خرجت إلي كأنك فتى. فقال صلى الله عليه وآله: نعم يا أعرابي أنا الفتى، ابن الفتى، أخو الفتى. فقال: يا محمد أما الفتى فنعم، وكيف ابن الفتى وأخو الفتى؟ فقال: أما سمعت الله عز وجل يقول: " قالوا سمعنا فتى يذكرهم يقال له إبراهيم   " فأنا ابن إبراهيم، وأما أخو الفتى فإن مناديا نادى في السماء يوم أحد " لا سيف إلا ذو الفقار ولا فتى إلا علي، فعلي أخي وأنا أخوه.
1.	We were told by Hasan bin Ahmad bin Idrees, may Allah be pleased with him, that he said: We were told by my father, from Muhammed ibn Hussain bin Abi’l-Khattab, and Ya’qoub bin Yazeed, and Muhammed bin Abi’s-Sibhan, all of them, from Muhammed bin Abi Umayr, from Aban bin Uthman, from al-Sadiq, Ja’far bin Muhammed, from his father, from his grandfather, peace be upon him, that he said: Indeed, an Arabian came to Allah’s Messenger, Allah’s blessings be upon him and his Family, and so he went out to him in red-dyed robe, and he said: O Muhammed, you have come out to me as if you are a young man. Then he, Allah’s blessings be upon him and his Family, said: Yes, O Arabian, I am the Young Man, son of the Young Man, brother of the Young Man. Then he said: O Muhammed, as for (that you are) the Young Man, then yes. But how (are you) the son of the Young Man and the brother of the Young Man? So he said: Have you not heard Allah, Exalted and Glorious is He, saying: «They said: We heard a young man mentioning them, who is called Ibrahim» (21:60)? So, I am the son of Ibrahim, and as for (me being) the brother of the Young Man, a caller, indeed, cried from Heaven on the Day of Uhud: «There is no sword but Dhu’l-Faqar, and there is no Young Man but Ali». Hence, Ali is my brother and I am his brother.
