Use of Credit Cards

AOA! I have a question regarding the use of credit cards within the boundaries of Islamic principles. In today’s modern world, credit cards have become an integral part of financial transactions. However, I seek guidance from knowledgeable Islamic scholars regarding their permissibility and any potential pitfalls associated with their usage.

  1. Can we use credit cards for everyday transactions without falling into riba (usury/interest)?
  2. What are the alternatives to credit cards that are in line with Islamic principles?
  3. Are there any specific conditions or guidelines we should follow when using credit cards?
  4. Is it permissible to use credit cards for emergency situations or for convenience?
