Re: black magic and Jadoo
I’ve heard that the reason why the magician may attempt to strike again is because the jinn he assigned to the victim to cause him/her pain goes through takleef when the victim starts doing ruqya and reciting Quran/etc. So, the jinn goes back to the saahir and the sahir may attempt to refresh the magic.
But one shouldn’t “obsess” over this thought. Dua and Allah’s kalaam are both powerful and a sincere dua to Allah to remove all traces of jadoo permanently can render the sahir’s attempts futile. In other words, Allah has the power to stop the sahir in his tracks so all his subsequent efforts are unsuccessful. If we fear that “Oh no saahir will attack again”…ithis fear and mayoosi is not healthy. When we do an amal to combat magic, we should do it with full yaqeen that Allah will cure it completely. But the victim should learn from this experience in that he/she needs to be regular in their ibadat (namaz etc) even after completing the amal.
