Does this true authority (al-wilayah al-haqqah) belong to anyone other than our master the Commander of the Faithful?

And who is famously known as the Guardian (al-Wali) and to whom authority (al-wilayah) is obligatory other than him? For these widely transmitted (mutawatir) sayings of the Messenger—Exalted is His might—are the best witness to the soundness of that. And it has come in the book Mashariq al-Anwar: “Because the authority of Ali is the light of the Lord.”

The Second Verse: [“Say, 'If the sea were ink for the words of my Lord, the sea would be exhausted before the words of my Lord were exhausted, even if We brought the like of it as a supplement.'”] ¹
