Al-Tufayl, who was the nephew of Sayyidah Juwayriyah (may Allah be pleased with her), narrates from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "Whoever wears silk in this world, Allah Almighty will clothe him on the Day of Resurrection with a garment of fire," or (he said): "a garment of His fire."
