Imam Ali (ع) in the Torāh of Musa b. Imrān (ع) - Non Shia source: Hadith
The following is narrated from the Mukhalifeen, Arabic will follow:
Abu Bakr Al-Shirāzi (from the city of Shirāz, a great Hāfith from the Mukhālifeen) has narrated on what has been revealed in the Quran concerning Amir Al-Mumineen (ع), narrated from the Maqātil, from ‘Atāah, concerning the following verse of the Holy Quran in Surāh Al-Baqārah, Verse 53:
And when We gave Musa the Book and the distinction that you might walk aright. (Sahih International)
It was written in the Torāh of Musa b. Imrān (ع): O Musa, I have chosen you & have chosen your representative, and he is your brother - Hārun - from your father & mother. The same way I have chosen for Muhāmmad Īliyiā (Ali in the Torāh), he is his brother and his successor, representative, and caliphate after him. Blessed Are you two for the brothers you have, and blessed they are to have you. Īliyiā, the father of the Al-Sibtāan (Kunyāh of Imam Ali [ع]), Al-Hassan & Al-Hussain, and Al-Muhāsin the third of his sons. He is just like your brother Hārūn, I have given him Shabārāh, Shābeer, and Mushābirāh.

أبو بكر الشيرازي فيما نزل من القرآن في أمير المؤمنين (ع)، عن مقاتل، عن عطاء في قوله تعالى: {ولقد آتينا موسى الكتاب}.
كان في التوراة: يا موسى إني اخترتك واخترت لك وزيرا هو أخوك - يعني هارون - لأبيك وأمك، كما اخترت لمحمد إليا، هو أخوه، ووزيره ووصيه، والخليفة من بعده طوبى لكما من أخوين، وطوبى لهما من أخوين، إليا أبو السبطين الحسن والحسين، ومحسن الثالث من ولده كما جعلت لأخيك هارون شبرا وشبيرا ومشبرا.
