Happy Society & Spread of Love and Morality
With the establishment of Imam Mahdi's governance, the atmosphere of friendship and brotherhood will spread all over the world. There will be such a justice that everyone will take his or her own right. Balance will be established in the entire human society. During the appearance of Imam Mahdi(a.s.), people will enjoy divine blessings equally, and no right will be trampled.
With the blessings of Imam Mahdi(a.s.), the intellects of people will be perfected and their morals will attain completion. (Bihaar al-Anwaar, vol. 52, p. 328 & 336)
None will desire supremacy and superiority over the other. (Bihaar al-Anwaar, vol. 52, p. 385)
Due to the blessings of Imam Mahdi, people's hearts will be filled with mutual love and unity. (Bihaar al-Anwaar, vol. 53, p. 187; Mikyaal al-Makaarem, vol. 1, p. 52)
The Spring of Knowledge
The period of Imam Mahdi's appearance is referred to as the spring of knowledge. According to Islamic narrations, under Imam Mahdi's leadership, human beings achieve intellectual perfection and thus a speedy growth will occure in human intellect and knowledge.
Like justice and equity, Imam Mahdi (a.s.) will spread knowledge throughout the world. (Behaar al-Anwaar, vol. 36, p. 253.)
Before His appearance, The Almighty God has granted only two parts of knowledge to the humanity. Besides these two, twenty-five (25) more parts will be manifested through Imam Mahdi(a.s.). (Behaar al-Anwaar, vol. 52, p. 336; Mikyaal al-Makaarem, vol. 1, p. 235.)
Bountiful Wealth & Economic Welfare
Wealth is an important desire of human beings. Many fighting and wars are rooted in the greed beyond wealth. At the time of Imam Mahdi (a.s.) the plentiful resources of the earth will be discovered, distributed, and evenly and wisley utilized.
Imam Mahdi (a.s.) will dispense wealth equally among the people. (Mikyaal al-Makaarim, vol. 1, p. 101; E'qdal-Dorar, p. 40.)
Economic welfare will attain such heights that none eligible for Zakaat(religious tax) will be found. (Behaar al-Anwaar, vol. 52, p. 339 and 390; Mikyaal al-Makaarim, vol. 1, p. 234; E'qd al-Dorar, p. 171.)
The Earth, Endowments and Harmony with Nature
Nature is loosing its cleanness and decency. Misuses by human beings have developed concerns about the conservation of the earth and its resources. At the time of Imam Mahdi(a.s.) the world will be revitalized in all aspects.
The hidden treasures and mines of the earth will come to the fore. People will actually see these treasures above the ground. (Mikyaal al-Makaarim, vol 1, p 46.)
The world will be revitalized by the implementation of justice, the sky will send down abundant rain, trees will reveal their fruit, and the earth will deliver her plants, embellishing herself for her inhabitants.
