[Pooya/Ali Commentary 39:55] The best among the created beings sent down to the people is the Holy Prophet with the book of Allah. The Holy Prophet, on several occasions, made known to the people that Ali and he were from one an the same light, so they should follow and obey him (see hadith al thaqalayn and other traditions, the commentary of al Ma-idah: 67, Ali Imran: 61, Ahzab: 33, Baqarah : 124, and recall to memory the commentary of several verses so far read), and after Ali, the holy Imams of the Ahl ul Bayt. They are the best among the whole mankind in all ages. To follow the best chosen by Allah, we must identify and discard those who are ordinary and weak in faith.
