after the prophet. According to al-Baqir, the prophet has revealed the religion but in every age there must be an Imam who leads to the religion and verse 13:7 refers to Imam. A hadith narrates that "He who knows himself knows his Lord.", but knowing Allah without His theophanic form (Mazhar), the Face of Allah, is impossible. Imam is the one who carries the human knowledge of Allah, without him we will be trapped in ta'til or metaphysical idolatry (tashbih)." Numerous Shia hadith narrate: The Quran is the silent Imam, the Imam is the speaking Quran; Imam is the Guide by whom Quran remains alive. Regarding this matter, Mulla Sadra believes that the earth can not be without an Imam otherwise, the Quran will die. By Shia, Wali is the one who has the most love and devotion to God, so God has bestowed His knowledge upon him. Hujjah The Hujja means the proof or God's guarantee to men; as the presence of the Hujja, whether hidden or apparent, is necessary for all times, this presence expresses the metaphysical reality of the Hujja and the inseparability of the prophetology from Imamology. Al-Baqir stated, "...Imam is the Proof of Allah to His servants and the earth will not remain without the Proof of Allah to His servants". From the Time of Adam, Allah has sent Imams to guide the people towards Him who are His Hujjah upon His worshippers. Khomeni described "Proof of Allah" as follows: "A ‘Proof of Allah’ is one whom Allah has designated to conduct affairs, all his deeds, actions and sayings constitute a proof for the Muslims. If someone commits an offense, will be made to the ‘proof’ for adducing evidence and formulating the charge. If the ‘proof’ commands you to perform a certain act, to implement the penal provisions of the law in a certain way, or to spend the income derived from booty, zakat and sadaqa in a certain manner and if you fail to obey him in any of these respects, then God Almighty will advance a ‘proof’ against you on the day of Judgment". Political aspect The Shia believe that only the divinely chosen one is the legitimate leader of the community who owns some spiritual gifts. The first of these leaders was Ali ibn Abi Talib and his successors were the descendants of the prophet and the heirs of the charisma of
