Wikipedia on “Puranas” have shown classification of the Mahapuranas on the basis of the three gunas of Sat, Rajo and Tamo with the caveat “Scholars consider the Sattva-Rajas-Tamas classification as "entirely fanciful" and there is nothing in each text that actually justifies this classification.”
Sattva ("truth") : Vishnu Purana, Bhagavata Purana, Naradeya Purana, Garuda Purana, Padma Purana, Varaha Purana
Rajas ("passion"): Brahmanda Purana, Brahma Vaivarta Purana, Markandeya Purana, Bhavishya Purana, Vamana Purana, Brahma Purana
Tamas ("ignorance"): Matsya Purana, Kurma purana, Linga Purana, Shiva Purana, Skanda Purana, Agni Purana
[Since Wikipedia is not the final word on our Puranas, hence this question]
My question is, “Are there any commentaries, shrutis or other scriptural references for this classification?”
