Hi mddilnawazrafi
Welcome to the Apple Community.
Your Apple ID is the account you use to access Apple services,
like the App Store, Apple Music, iCloud, iMessage, FaceTime, and more.
Apple require you to have a payment method listed in your account,
for the first time you use the App Store etc., even if you are just downloading free apps.
Check the payment methods that you can use with your Apple ID:
(NB: Scroll to your country or region to see what payment methods are available.
.... Eg: you may be able to use a gift card for the payment method if acceptable in your country.)
