Matsyapurana 11.11

11.11

pūrvo manustu cakṣāma na yamaḥ krodhamūrchitaḥ
saṃtarjayāmāsa tadā pādamudyamya dakṣiṇam //

The Sun mistaking Chhâyâ for Saṃjñâ begot from her Sâvarṇi Manu so called because he is of the same Varna as Vaivasvata Manu and Śani, and also the two girls, named Tapatî and Viṣṭi. When Chhâyâ herself became the mother of these children, she began to devote more attention to her own offspring than to the progeny of Saṃjñâ. Manu did not mind this, but Yama took it seriously, and one day he lifted his right leg to kick Chhâyâ. Chhâyâ also, getting in a fit of rage, cursed Yama, and said that his leg would be eaten by worms and would always discharge pus and blood.—8-12.
