Amaliyaat
Q: I read somewhere that doing the following Amal can break any black magic spells,
• Take a glass of water
• Recite darood sharif 11 times
• Recite bismillah hir rahmaan nir raheem 487 times
• Recite darood sharif 11 times (again)
• Blow 3 times on water and drink (Or give to someone affected to drink)
If you see bright whiteness then it means that the magic got extinguished. Just like water extinguishes fire. Is this Amal valid? Can I rely on this Amal?
