Protection Against Jinn with Regard to Non-Muslims

As-salamu `alaykum.For nearly 2 weeks. I?m seeking the answer of a question  that comes to my mind described in the following paragraphs:As far as I knowFrom www.IslamOnline.net (Search : ?jinn paralyses?)?Because jinn can see us while we cannot see them, the Prophet (peace and blessings be upon him) taught us many ways to protect ourselves from their harm. They are seeking the refuge of Allah from the accursed Satan, reciting Surat Al-Falaq and Surat An-Nas, and reciting the words taught by Allah in the Qur?an. Allah Almighty says, ?And say: My Lord! I seek refuge in Thee from suggestions of the evil ones. And I seek refuge in Thee, my Lord, lest they be present with me.? (Al-Mu?minun: 97-98)?Saying bismillah, (in the name of Allah) before entering one?s home, eating or drinking, and having intercourse will keep Satan from entering the house or partaking with a person in his food, drink and sexual activity. Similarly, mentioning the name of Allah before entering the toilet or taking off one?s clothes will prevent the jinn from seeing a person in a state of undress or harming him?And I also know that from www.IslamOnline.net?We have in the traditions of our prophet (pbuh) and the biography of early Muslim physicians much evidences to the value of reading the Quran and using its verses as therapy and a form of exorcism.?So,  if we evaluate all the informations above we can come to a conclusion that ?Alhamdulilah we are muslims. We dont have to fear from jinns. As our Prophet taught us many ways to protect ourselves from their harm. Even in  case of a jinn possession, reading the Quran and using its verses as therapy and a form of exorcism would In sha Allah help us?.(Coming to my question :)?However, I could had been borned to be a non-muslim (Budhist, Shamanist, Christian, Jewish, any religion and belief). I could had no knowledge, lack of knowledge or misunderstanding about Islam. If  I were a non-muslim, would  not I have been protected against jinns and gotten heal from jinns possessions? In another words,  are there any protection ways for non-muslisms like muslims (the ways our prophet taught us) and how  could non-muslims heal from the jinn possessions (muslims by reading Quran) ? Is Allah merciful to the non-muslims as just as to the muslims in this issue??I would be pleased if you can make a clarification on this issue by considering the following time intervals (Satan excites apprehension ) : ? The History before existence of Islam (Pre-Islam. I could had been borned anytime in the history before Islam as a non-muslim and had no knowledge on God and any prophet), ? History from the existence of Islam till today, ? Today and the future. Thanks a lot. May Allah be with us.
