It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) suffered from an eye inflammation, or one of his family or Companions did, he (peace and blessings be upon him) would supplicate with these words: 'Allahumma matti'ni bi-basari waj'alhu al-waritha minni, wa arini fil-'aduwwi tha'ri, wansurni 'ala man zalamani' (O Allah, let me enjoy my eyesight and make it my heir (that is, keep it sound until my death), show me my revenge upon the enemy, and help me against whoever has wronged me).

It is narrated from Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that he said: "Whoever hears someone sneeze and says (in response): 'Al-hamdu lillahi 'ala kulli hal' (All praise is for Allah in every state), will never suffer from toothache or earache."
