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 ‘alayhi wa sallam, is His slave and Messenger.
Imaam Ibn Hajar reported in his book Al-Fath from Wahb Ibn Munaabbih the way of using Sidr leaves (Lotus jujube) as a remedy to be rid of bewitchment. He said, “One should take seven leaves of green Lotus jujube, grind them between two stones, put the stones and the leaves in some water, then take out the two stones. Having done so, he should recite the verse of the Kursi (Chair) [Quran 2:255] and the last three chapters of the Quran [Quran 112,113,114]"
Following this, he should drink three sips of that water and shower with it and by the permission of Allaah, everything that he was afflicted with will be gone.
This treatment is particularly useful for male impotence.
Allaah Knows best.
