SB 9.4.38
muhurtardhavasistayam
dvadasyam paranam prati
cintayam asa dharma-jño
dvijais tad-dharma-sankate
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In the meantime, only a muhurta of the Dvadasi day was left on which to break the fast. Consequently, it was imperative that the fast be broken immediately. In this dangerous situation, the King consulted learned brahmanas.
