"The Messenger of Allah [SAW] said: 'Do not be so close to the Mushrikin that you can benefit from the light of their fires, and do not engrave Arabic (words) on your rings.'" (Using translation from Nasāʾī 5209)  

قَالَ رَسُولُ اللهِ ﷺ «لَا تَسْتَضِيئُوا بِنَارِ الْشِّرْكِ وَلَا تَنْقُشُوا عَلَى خَوَاتِمِكُمْ عَرَبِيًّا»
