There's no such thing as "Waseela". Its all pre-destined. Way I see things (and I'm no Aalim), ISLAM is the only religion, where you do not need any Waseela.. Its just you and your LORD. No one else. As soon as you fall into this "Waseela" thing, you tend to divert from the real truth, which is, NO ONE can get you anything by any means, except what ALLAH wishes.
I do not wish to open a whole new topic of this "Waseela" and how certain people, from certain sects of a religion think this life is ALL about a Waseela. Just because of the Waseela thing, we've come to a point, where people goto Mazaars and people ask from "DEAD" to ask Allah for certain thing. This is straight shirk ( in my opinion and many Ulama teaches that too) and shirk is one of the Major sin.
I'm not too sure about your "Spirit of Shaheed can move around part". Their work in this world is done. They accomplished what they came for. Also, YOU and I do not know who's "SHAHEED" and who's not. No one knows, but Allah and HIS messenger.
Allah s.w.t knows best :)
waseela's are definitely used by people in Islam.You dont need to open a topic if u understand this example.
Hazrat Muhammad (SAW) asked Hazrat Awaais karni (R.A) to pray for the forgiveness of Ummah of Hazrat Muhammad (SAW) and thus made Hazrat Karni (R.A) a waseela for his Ummah.
If you still want to discuss is upto you.
Recently,people use waseela as Aulia-Karam and go their shrines and ask Aulia karam to pray for them. Going to Aulia-Karam is not shirk, search online otherwise discuss.
Since only Ilm-ul-Ghaib is known by ALLAH, a part or any part of it can be shared by anyone whom ALLAH desires. You and I maynot know,we are worthless creatures, but pious people of ALLAH surely know and can help in this regard.
It has been related by ad-Daylami on the authority of Abu Hurayra who said that the Messenger of Allah, may Allah bless him and grant him peace said:
“Indeed from knowledge, there is a part which is concealed, which no one knows it except the Knowers of Allah. For when they speak on it, no one rejects it except the people completely heedless of Allah.”
