Question
What is the validity of the prohibition against entering the restroom at the time of the adhan due to the gathering of devils there? Is there any rational or textual evidence for this?
Answer
I say, and with God's success: The original ruling is permissibility, and nothing prevents entering the restroom at the time of the call to prayer except for the etiquette with the call to prayer. Whoever wants to say otherwise must provide evidence for it, and God knows best.
