2.35.18

dāha (bali) statra na kartavyo vipradisarvajātiṣu /
dīyate na jalaṃ tatra aśubhaṃ jāyate dhruvam /
lokayātrā na kartavyā duḥ khārtaḥ svajano yadi //

Cremation must not be performed then among all castes, beginning with Brahmins; / water is not offered then; misfortune certainly arises; / the funeral procession should not be carried out if the kin are stricken with grief.
