وَعَنْ أَنَسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ أَمْثَلَ مَا تَدَاوَيْتُمْ بِهِ الْحجامَة والقُسْط البحري» Anas reported God's messenger as saying, "The best medical treatments you apply are cupping and sea costus.” (Bukhari and Muslim.) — Mishkat al-Masabih, Hadith 4328
