Paying zakaah via credit card

I was wondering if it was permissible to pay zakah using a credit card since i have the funds to do so and can pill the bill without any interest.

Praise be to Allaah.

Firstly: 

It is not permissible to subscribe to credit cards unless one is forced to do so, because this is a riba-based contract, and riba is haraam according to the Qur’aan, Sunnah and scholarly consensus. 

See questions no. 13735, 13725 and 3402. 

Secondly: 

With regard to paying zakaah via credit card, if you have money saved to cover what you are going to pay, so that you will not have to pay any interest – as you mention in the question – then there is nothing wrong with paying zakaah by this method. 

But if you do not have money saved to cover what you are going to pay, then this is considered to be a loan with interest from the bank, which is riba and is haraam, so it is not permissible for you to pay zakaah or anything else by this method. Allaah is Good and does not accept anything but that which is good. 

And Allaah knows best.
