Although the inscription on the ring of the Messenger of Allah (peace be upon him) was only Mohammad Rasool Allah (Mohammad is the Messenger of Allah), it is reported that whenever the Messenger of Allah (peace be upon him) entered the privy to answer the call of nature, he (peace be upon him) would remove his ring.

In light of the above practice and Sunnah of the Messenger of Allah, if one adorns a ring with the Blessed Name of Allah, or His Messenger (saws), or any Verses of the Glorious Quran, etc., it would be preferred that one remove their ring before they enter the toilets.

It is permissible for you to wear a chain Allah’s Name is written on it provided there should not be any disrespect to it.
