Forty Keys of Luminous Ta’wil

Excerpt:

What wisdom was hidden in covering the five holy persons with the same mantle?

The holy Prophet by this act alluded to the ta’wīl that [spiritually] they were the members of his house and their light is one in the Sacred Sanctuary. That is, their luminous house is the Sacred Sanctuary and with respect to this luminous house, they are called Panj-tan-i Pāk or the five holy persons.
