Answered by Shaykh Faraz Rabbani
Can a Muslim wear a necklace, ring, etc that has the name of Allah written on it during her everyday life?
In the Name of Allah, with blessings & peace on the Beloved of Allah, and his folk and all lovers of Allah
Walaikum assalam,
Yes, it is permitted for women to wear such jewelry. [Ibn Abidin, Radd al-Muhtar] However, it needs to be covered up (or taken off) before entering toilets. [ibid.; Shurunbulali, Imdad al-Fattah]
And Allah alone gives success.
Wassalam.
