Sheikhana Ahsanallahu ilaykum. What are the rules in Germany for opening a bank account? There are some Islamic banks where someone might be able to avoid one or two things that you would normally have at a regular bank. And it would make it a bit more difficult.

Ustadh AbdulAziz al-Haqqan

It becomes obligatory to deal with the Islamic bank, that being said still choose the options that are safe from riba etc.
