Re: Do jinns exists
No doubt SATAN is a jinn in Surah Kahf ayat or sign 50(I wont write verses anymore now:) ) . Well Jinn do exist and no denial of it ahadith is proven that.
Now yes waswasa in our heart Al Nas surah the very meaning of it gives you they can create waswasa but Satan can by Jinn as well as Human i think so its in Surah 6 aya 128 or 28. I am not sure.
Jinns exist another proof when Prophet recited the Quran the Jinns as in the Quran did talk amongst themselves what a beautiful recitation this is. Anyways even doing your prayer time this is again Sahih hadeeth from Sahih Bukhari, that there is a Satan called as KANZAAB who stand upright and blows waswasa into your years.
Other observable phenonmenad during the time of Salah is that mind tends to deviate on such things, and thoughts which havent hit your mind during the time of Salah. Well other than tht Allaah knows the best.
