Islam does not deny the existence of Jinn rather there is a complete in the holy Quran “Sura Jinn” but it doesn’t mean Allah has created them without purpose and as it is very common amongst people that Jinn do this or that. It’s not true. Still if there is any such problem one has seen, we have many Duas and Zikr that should be recited not only when people get in trouble but even in there every day life schedule it has recommended that we should recite such Duas and verses of the Holy Quran to keep us safe. As if you see “Sura An Nas” it has said about the evil whisper of Shaitan and Jin but we have to understand what does it mean by evil whispers of Shaitan. It’s all about distraction of faith from them but not to make anyone scared.
مِن شَرِّ الْوَسْوَاسِ الْخَنَّاسِ
From the evil of the whisperings of the slinking (Shaitan),
الَّذِي يُوَسْوِسُ فِي صُدُورِ النَّاسِ
Who whispers into the hearts of men,
مِنَ الْجِنَّةِ وَالنَّاسِ
From among the jinn and the men.
So as long as jinn can whisper in someone’s breast even man can do the same.
