I've not looked into the specifics of religious accommodation law with regards to airline delays, but I doubt the airline would have a problem if you needed to stay on the ground a bit longer due to a delay if there was some kind of IRROPS. Most folks are looking to get on the soonest possible flight, so you may actually be helping the airline by saying you'll take a flight 48 hours later or whatever.

This "principle" does not apply in the EU, where the airline has a duty of care (including hotels) regardless of the reason for the delay.
