Q: Is it permissible
to enter the toilet while wearing a necklace with the name of Allah or the Prophet or some Ayahs (Qur'anic verses) on it?
All Praise is due to Allah Alone and peace and blessings be upon His Messenger, his family, and Companions.
Doing so is Makruh (disliked). However, there is a Rukhsah (concession) in case of fearing loss (Part No. 5; Page No. 96) that a person may enter the toilet while wearing such a necklace so as to preserve it.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
