First Mention of Dua - First time when it was mentioned that someone's dua is with Mauli and it saved her from that chandelier incidence. Nandini's dua gave Mauli a new life, Mauli is alive because of Nandini's dua
Second Mention of dua - It is by none other than last heiress of Shakuni ie Dida, Dida says Mauli got the baby because someone's dua is with her. Can you imagine Nandini's dua can't only save Mauli but she can plant a baby in her womb.
Kunal to aise hi kheer aur Saree ko praise karta hai, don't you think Nandini's dua will help
him fulfill his dream of treating patients for free? Who knows he chose Nandini over Mauli, for this purpose only.
