Sometimes one may use water mixed with Sidr (lote-tree) leaves on which Quranic verses are recited to undo magic. Should he wash himself with it cold or can he add to it some hot water on which no Quranic verses have been recited? Does it make a difference if it is used for three, or two or one day?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu 'alyhi wa sallam, is His slave and Messenger.

There is no harm for the Muslim to add hot water on which Quranic verses have not been recited to the water on which verses of the Ruqyah have been recited. It is not harmful when a person washes himself with that water for three days instead of two because the Islamic Sharee‘ah has not specified the period of Ruqyah to be two or three days. The important thing is that the Ruqyah is given, and there is no harm in repeating it when needed. You should earnestly supplicate to Allaah The Almighty and entrust the matter to Him. Indeed, He is the Effecter of the causes who answers the supplications of the distressed and alleviates their distress. So, combine between the Sharee‘ah-approved Ruqyah and fully relying on Allaah The Almighty.

Allaah Knows best.
