How can I make a dua when starting my fast?

To make a dua when starting your fast, you can say a simple prayer asking for Allah's blessings and guidance during your fast. You can also recite specific duas recommended by Prophet Muhammad (peace be upon him) such as "Allahumma inni nawaitu sawma ghadin an adai fardi Ramadan" which means "O Allah, I intend to fast tomorrow in fulfillment of my obligation in Ramadan."
