Answered by Ustadh Salman Younas
Question: Is it haram to get two sisters married the same day?
Answer: assalamu `alaykum
I have found nothing to support such a claim. Believing that it is religiously impermissible to have two sisters get married on the same day would be an innovation in light of the fact that there is no basis for such a belief.
