Authentic Sa'idi ethmid kohl With Zamzam water This kohl, God willing, is guaranteed authentic and 100% pure. I personally buy the raw stone, soak it in Zamzam water for several months, filter it from attached stones, then grind it. By God's grace, it has been tested and benefited many people. I have 30 years of experience in this, all praise be to God. I am specialized in producing authentic ethmid. And if God wills, I always prioritize fearing God above all.
