Markandeyapurana 16.50

The son spoke:
She, propitiated by them when they resorted to her, said “Let your wish be asked for.” The gods petitioned for day, saying “Let it be as before!”

Anasūyā spoke:
“The might of a faithful wife may not be lost in any wise. Hence while honouring that good lady, I will liberate the day, O ye gods! that day and night may again exist, and that that good lady’s own husband shall not perish.”
