Shaykh ibn al jawzi stated in his book .. While he was in Mecca, once fell sick and had no access to a doctor or medicine. So he used to seek a cure in The AI-Fatihah by sipping a drink from the well of Zamzam that recited the AI-Fatihah on. he got complete cure in this method and he used to rely on it whenever he felt pain. This cure always helped him
(The prophetic medicine)
Indeed, AI-Fatihah is the best cure because it contains sincere servitude to Allah, praising Him, relating all bounties to Him, seeking His help and support, and invoking Him for all types of advantages, such as the correct guidance that brings about benefit and fends off torment.
It was reported that the part in AI-Fatihah that contains the Islamic prayer formula is what Allah said: “You (Alone) we worship, and You (Alone) we ask for help (for everything).” (1:5)
ايَّاكَ نَعْبُدُ وإِيَّاكَ نَسْتَعِينُ
Indeed, these are mighty powerful words that contain the strongest medicine contained in this chapter. These words entail sincere dependence and reliance o Allah, seeking refuge and help from Him and showing meekness and need of Him. Consequently, these words contain the best goals to seek, which is worshiping Allah Alone. In addition they contain the best method to acquire
these goals, that is, invoking Allah for His support so that one achieves these goals. There is a wonderful secret in using the AIFatihah as an Islamic prayer formula to treat poisons, and
Allah has created a cure for every disease.
