Answer
In order to protect oneself from black magic and Jinn, the following is advised:
1. Be obedient to Almighty Allah Ta’ala and fulfil all His ordains. Perform the five times Salaat. In the case of a male, perform Salaat with Jamaat in the Musjid.
2. Always remain in the state of Wudhu.
3. Recite the Qur’aan abundantly, at least one Juz everyday.
4. Recite Aayaatul Kursi after every Fardh Salaat.
5. Recite the four Quls every night before sleeping and blow on oneself.
If the above points are carried out, Insha Allah, one will be saved and protected. If one is still affected with black magic, then it is the Will of Allah.
and Allah Ta’ala Knows Best
