What is the solution to the deviancy of the Ummah?

The following steps have to be taken as solutions:

1. Return to the Qur’an and Sunnah.
2. All practices should be in accordance with Sunnah – Islam has not rejected cultural practices, but cancels where it is inappropriate.
3. Fanatical factionalism – One cannot be left to his opinion, but have to be united upon the truth.
