SB 9.8.3
vrddham tam pañcatam praptam
mahisy anumarisyati
aurvena janatatmanam
prajavantam nivarita
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Bahuka died when he was old, and one of his wives wanted to die with him, following the sati rite. At that time, however, Aurva Muni, knowing her to be pregnant, forbade her to die.
