If you are effected by bad and harmful Jinns you may recite the following.
Recite 3 times;
“Audhu billah min ash-shaytan ir-rajeem Bismillahi ‘r-Rahmani ‘r-Raheem bismillahi alladhee la yadurru ma` ismuhu shayun fi ’l-ard wa la fi ’s-sama wa huwa as–samee` ul-`aleem.”
Ayatul Kursi 7x
Salaamun Qawlam Mir Rabbir Raheem x 15
Yaa Wadood x 300
And blow it on yourself, morning, noon and evening. This will burn the Jinn and not to be entering to it harming you. Anyone affected you may recite this on them. After several days Insha’Allah the Jinn will burn or run away.
