Are all the present
Kafirs (disbelievers) or just their Imams?
Shiites nowadays have many sects. For more clarification on this issue, refer to the contemporary books written on deviant sects, and you could also read Mukhtasar Al-Tuhfah Al-Ithna `Ashriyyah and Al-Khutut Al-`Aridah by
Muhibb Al-Din (Part No. 2; Page No. 375) Al-Khatib, Minhaj Al-Sunnah by
Ibn Taymiyyah, and its abridged version, Al-Muntaqa by
Al-Dhahaby. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
