The word “Shia” means “followers; members of party”. As such, the term “Shia” alone has no negative or positive meaning unless we specify the leader of the party. If one is a Shia (follower) of the most righteous servants, then there is nothing wrong with being Shia, specially if the leader of such party has been assigned by Allah. On the other hand, if one becomes the Shia a tyrant or a wrong-doer, he shall meet with the fate of his leader. In fact, Quran indicates that on the day of Judgment people will come in groups, and each group has its leader in front of it.
Allah, to whom belong Might and Majesty, said:
One day We shall call every group of people by their respective Imams. (Quran 17:71)
In the day of judgment, the destiny of the “followers” of each group highly depends on the destiny of his Imam (provided that they really followed that Imam). Allah mentioned in Quran that there are two types of Imams. Some Imams are those who invite people to Hell fire. They are tyrannical leaders of each era (like Pharaoh, etc.):
And We made them (but) Imams inviting to the Fire; and on the Day of Judgment no help shall they find. In this world We continued to curse them; and on the Day of Judgment they will be among the hateful. (Quran 28:41-42).
Certainly, being the members of the parties of such Satanic Imams has been severely denounced in Quran, and the followers of such parties will meet the fate of their leaders. However, Quran also reminds that there are Imams who are appointed by Allah as Guides for the mankind:
“And We ASSIGNED from among them some Imams who GUIDE by Our authority since they were patient and believed firmly in Our Signs.” (Quran 32:24)
Certainly, the true followers (Shia) of these Imams will be the real prosperous on the day of resurrection. Thus being a Shia does not mean anything, unless we know the Shia of whom. Allah mentioned in Quran that Some of His righteous servants were Shia of His other righteous servants. An example was Prophet Abraham who was mentioned in Quran specifically as the Shia of Noah:
“And most surely Abraham was among the Shia of him (i.e., Noah)” (Quran 37:83)
