In the last verse of the holy chapter of Al-Bayyina (The Clear Proof), it is mentioned that those whose motives of movement is the holy Quran- they are the doer of what Quran orders and asks them to do. It is one motive for us, 124 thousands prophets are the motives for us, the twelve Imams are the motives for us, and the religious scholars are the motives for us toward the Almighty Allah. If we keep in touch with these motives and utilize them to move forward, we will reach the faith- faith means believing in Allah, the day of resurrection, the divine prophets, the Holy Quran and the angels.
