[Pooya/Ali Commentary 55:20] Aqa Mahdi Puya says: According to the Ahl ul Bayt the two streams refer to nabuwwah (prophethood) and imamah (divinely commissioned guides) which flow together and yet with a distinguishing line between them, assigning separate functions to each of them, so as not to create confusion. The Holy Prophet is the most perfect manifestation of nabuwwah and Ali is the most perfect manifestation of wilayah or imamah, and Fatimah is the distinguishing line between them which connects both of them. According to a tradition related by Salman Farsi, Ibn Jubayr and Sufyan Sawri recorded by Ibn Marduwayh and Jalal al Din al Suyuti the two oceans are Ali and Fatimah and the Holy Prophet is the link between them, Hasan and Husayn are the pearls.
