The Ruling on Parties and Groups in Light of the Hadith of the Sects

Question:
And it is not a condition, may Allah reward you. Are the parties and groups that exist in our time considered among the sects, such that there is no harm in them being in the Fire except for one?

Answer:
The Messenger (peace and blessings be upon him) gave us the criterion for this: What he (peace and blessings be upon him) and his Companions were upon is from the saved sect, and whoever opposes what the Messenger (peace and blessings be upon him) was upon is from these sects. So one looks at these groups, what they are upon, and what they call to, and rules upon them based on that.
