Q: I have qadaah fasts. Am I allowed to keep the Muharram fast or do I need to complete my outstanding fasts first?
A. It is better for you to do the qadha fasts. You may do the qadha fast with the Muharram Aashura fasts. According to some Ulama you will receive the thawaab for both.
And Allah Ta’ala Knows Best
