Certainly, jinns can harm people, sometimes even causing death. They may throw stones or instill fear, as stated in the Sunnah and witnessed in reality.
For instance, during a battle, the Prophet Muhammad allowed one of his companions, a newlywed, to visit his wife. Upon arrival, the man found a snake in their bed. He killed it with a spear, but he died simultaneously. Upon hearing this, the Prophet prohibited killing jinns in homes except certain harmful snakes.
This incident shows that jinns can indeed harm humans, as reported in many narrations. They may pelt stones at people in deserted places or cause distressing noises like rustling trees. Sometimes, jinns may possess humans out of love or malice, as mentioned in the Quran.
Protection against jinns involves reciting specific verses from the Quran, such as Ayat Al-Kursi. (Surah 2: Aya 255) Reciting this verse at night shields one from harm until morning, as Allah protects those who seek refuge in Him.
In conclusion, while jinns may pose a threat, adhering to the teachings of the Sunnah and seeking refuge in Allah can safeguard against their harmful effects. Do jinns affect humans, and how can we protect ourselves from them?
