On the face of it, the question, Why did all the miracles stoped?, doesn't seem to have consumed much effort before and after it was posted, in term of the question, not the answer and comments it brought about.
The question in it's present state seems to be just a random claim which is not backed up by any reference and is limited to the scope of the a person's social exposure and beliefs (what (s)he considers to be a miracle etc), which too is not known. Therefore this question is definitely going to draw debate and slight, which is quite evident from the comments section under both the question and the answers.
As mentioned, the question can't, strictly and adequately, be answered and will mostly draw just information on the topic.
The question seems very weakly connected to Islam, which this site is about.
It is too broad, and opinion based.
How can this question be improved? Is it salvageable? Why should it be considered on-topic here? What more is fundamentally lacking in the question? Where am I not right in the points mentioned above?
