We must destroy all false beliefs that were added into Islam after the death of the Prophet (pbuh). We must be of the Muwahiddoon (the Unitarians of Islamic faith), who are the rejectors of sects. Allah Almighty says in the Quran: This Day I have perfected your Deen for you and chosen Al-Islam to be your Deen. (Quran, Surah Maidah) Nothing can be added or subtracted to Islam after this proclamation, and yet this is exactly what these various sects have done. Allah says in the Quran:And hold fast, all of you together, by the Rope of Allah and be not divided amongst yourselves. (Quran)
