let me see if i`ve got this right,what u are saying is,you do belive in spirits
No, we don't believe in spirits.
We believe in jinns, which are invisible beings that live alongside us even though we can't see them.
On top of that, each of us has our own personal jinn that we can't see that stays with us our whole life, called Qareen. On their own, jinns have no particular connection with the dead.
The way it has helped me,is that my dad passed when i was 17, and i`ve had messages from him to say he`s alive and ok,i know it to be him because he has told me personal things only he could know, i`ve also had messages from my grandads,nans,and one of my brothers all of who expect one nan,passed over before i was born.
However the mediums contact the non-Muslim jinns (Muslim jinns will never let themselves be contacted by humans). The non-Muslim jinns get personal info about the person you want to communicate with, say your father, from your father's qareen. That is how the medium will be able to give you startlingly accurate information that you know to be true about your father.
But you will believe that your father is sending you messages, when he isn't. It is the info they get from his qareen. Dead people are dead. They have no way of communicating with the living.
I can see where you're coming from, because you get great comfort from these messages you think you are getting from your loved ones. But your loved ones are in their graves, completely unaware of what is going on. They have no idea that you're getting any messages from them.
As I said before, then you begin to think that you can't do without these messages, until it prevents you from choosing the right path for your life and for yourself. Look what it's doing to you now. Also you believe that the medium is contacting the dead, when they are not, and that you believe that the medium somehow has knowledge of the unseen, when the only One that knows the unseen is Allah. It is disallowed because it involves deception (you think the dead are communicating with you), and there is no room for deception in Islam. Because it gets a hold on you. But mainly because it involves giving others the attributes of Allah, namely knowledge of the unseen, and that is a big sin known as shirk, and also disobeying His command, which is not to get involved in such things. Regardless of whether you think it's harmless, Allah has not allowed it, for all these reasons and more. So, if you become a Muslim, no you will not be able to go to a medium or spiritualist church.
You came into this world alone. You will depart this world alone. On the day of Judgement, you will stand up to answer for your deeds on your own, neither your parents brothers or sisters will help you, everyone will be too busy worrying about themselves. Allah says in the Qur'an: "But when the Shout comes. On the day when a man will flee from his brother. And his mother and his father. And his wife and his children. Every man that day will have enough concern to make him heedless (of others)." (Qur'an 80:33-37). So your relatives, for whom you are prepared to leave the guidance that Allah is showing you, even though they aren't telling you to, will not be able to help you on the Day of Judgement, indeed they won't even know what messages you're talking about, as they never sent you any, and also they'll be too worried about themselves. Think about it carefully.
In Islam, we respect our relatives and love them, and treat them the best we can while they're alive. After they die, we remember them and seek forgiveness for our Muslim relatives, but we leave them be. These are the best things we can do for them.
Now it's up to you, whether you want to take your life forward, start with a new and fresh beginning, and put yourself on the right path, obeying and worshipping your Creator without any associates in His Divinity, and to go to paradise, or whether you want to carry on as you are.
Take your time, read my posts again, digest them.
If you like everything you've seen about Islam so far, I wouldn't let my chance for guidance go for something like this. That would be a big loss for you indeed, both in this world and the hereafter.
Please keep reading and learning more about Islam, and don't give up now. You owe that much to yourself, at least.
