Cure for fever with al-Quran and sugar

Abu Abdullah (asws) has said to a man: ‘With what thing do you cure your sick when they have fever?’ He said, ‘May Allah (azwj) Keep you well, by these bitter medicines – by Safaayaj, and Al-Ghafas, and similar to these’. So he (asws) said: ‘Glory be to Allah (azwj), the One Who (azwj) has the Power to Free (Cure) with the bitter (medication) also has the Power to Free (Cure) with the sweet’. Then said: ‘If one of you has fever, so he should take a clean container, and place sugar in it, then recite over it what he knows from the Quran. Then he should place it underneath the stars (at night in the open), and place iron in it. So when it is the morning, pour some water on it and mix it with his hand, then drink it. So when it is the second night, increase another (piece of) sugar in it so it becomes two and a half times as much. So when it is the third night, increase another (piece of) sugar so it becomes three and a half times as much’.
