Sahada

Information

      لَا إِلٰهَ إِلَّا اللّٰهُ مُحَمَّدٌ رَسُولُ اللّٰهِ

As your brother, I must remind you gently:

✔ It is permissible to engrave the Shahada
✔ As long as the item will not be placed in disrespectful places, such as:

bathrooms

on the floor

mixed with non-Islamic religious items

Since this is a pendant / keychain / gift plaque, it is allowed and many Muslims do this.

But we just must treat it with respect.
