Protection from Black Magic

Recite Ayaat 81, 82 of Surah Yunus thrice

فَلَمَّا أَلْقَواْ قَالَ مُوسَى مَا جِئْتُم بِهِ السِّحْرُ إِنَّ اللّهَ سَيُبْطِلُهُ إِنَّ اللّهَ لاَ يُصْلِحُ عَمَلَ الْمُفْسِدِينَ

وَيُحِقُّ اللّهُ الْحَقَّ بِكَلِمَاتِهِ وَلَوْ كَرِهَ الْمُجْرِمُونَ

By reciting the above aayat thrice morning and evening, one is not afflicted by black magic. If one has already been afflicted, the effects will be removed.
