This is the Day of Resurrection, but you did not know.
This is the Day of Resurrection, but you did not know." (30:56) Imamat (leadership) will remain in the sons of Imam Ali (a.s.) exclusively, till the Day of Judgment and there will no prophet after Muhammad (s.a.). Wherefrom then have these ignorant people received the right to select Imams? " Imamat (leadership) is, certainly, the position of the prophets, and the inheritance of the successors.
Imamat (leadership) indeed, is the representation (khilafa) of Allah and the deputy of the Messenger (s.a.), and the office of Amir al-mu'minin (a.s.) and the inheritance of Imam al-Hasan and al-Husayn (a.s.) "Imamat (leadership) is, in fact, the reins of the religion, the social system of the Muslims. It is best for the world, and honor for the believers. Imamat (Islamic leadership) is Islam's maturing root, and its towering branch.
Through the Imam (a.s.) prayers are complete, Zakat, (charity) is paid, fasting, is maintained, Hajj is performed and Jihad, proper defense is exercised, the wealth of the nation (fay') and charity (sadaqat) are increased, the laws are enforced and the frontiers are protected and defended. "The Imam declares as lawful what Allah has done so and prohibits what Allah has prohibited.
He enforces the criminal laws of Allah, defends the religion of Allah and he provides guidance with wisdom, good advice and with the topmost strong evidence. "The Imam is like the risen sun that beautifies the world with its light and is in the horizon above the harm of hands and eyes. The Imam is as the bright moon, the shining lamp, the brilliant light, and the guiding star in the depth of darkness, in the middle of the towns, in the wilderness and the high seas.
The Imam is as crystal-clear water to thirst, an indicator of true guidance and the protector against destruction. The Imam is as fire of a lighthouse that provides warmth and guidance for those who seek heat protection against fatalities. Whoever would depart him would perish. "The Imam (in terms of blessings) is as the rain-bearing cloud, the drenching rainfall, the shining sun, the shadow providing sky, the open fields, the gushing forth spring, as a pond and a garden.
The Imam is as a comforting friend, a very kind father, a real brother, a tenderhearted mother of a small child, a refuge for people in disastrous conditions. The Imam is Allah's trustee over His creatures, His authority over His servants, His representative in His lands, the preacher of His cause and the defender of His sanctuary.
