Assalam-o-Alikumn everyone

I want to buy Samsung A70 in installment with 0% markup
I have an account in Meezan Bank and it's debit card.

Can anyone tell me the procedure and if it's safe to go for it?
I know Daraz offers their EMI service but it's only for Silk Bank users.
Further, I have looked i4u, LapNTab as well but they charge interest rate
