SB 10.7.22
muhurtam abhavad gostham
rajasa tamasavrtam
sutam yasoda napasyat
tasmin nyastavati yatah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
For a moment, the whole pasturing ground was overcast with dense darkness from the dust storm, and mother Yasoda was unable to find her son where she had placed Him.
