तदेनां पीडितां चेद्यः पतिर्भूत्वा न पालये । ततो यास्ये शास्त्रवादान्नरकांतं न संशयः
tadenāṃ pīḍitāṃ cedyaḥ patirbhūtvā na pālaye | tato yāsye śāstravādānnarakāṃtaṃ na saṃśayaḥ
Si quelqu’un, devenu époux, ne la protège pas lorsqu’elle est accablée, alors—selon l’enseignement des śāstras—il ira jusqu’aux confins de l’enfer ; il n’y a là aucun doute.
Lomaharṣaṇa (Sūta) (deduced for Māheśvara-khaṇḍa narrative frame)

No tīrtha is referenced; the verse is a dharma-śikṣā (ethical instruction).
None; it is a normative rule of conduct backed by śāstric authority.
