Purity: Ruling on Using Gold or Silver Objects Other Than Utensils
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 232
There is no problem in using the mouthpiece of a shisha pipe, the scabbard of a sword, a knife, or the frame of the Qur’an if they are made of silver or gold. However, the recommended precaution is not to use perfume and kohl containers made of gold or silver.
