How does Islam want to save the world?
There are different aspects to be'that. The beams of light that have emanated from be'that are more than a few. But today humanity needs two things that have their roots in be'that. One is promotion of thinking and the other is moral purification. If these two things are ensured, the old wishes of humanity will be fulfilled, justice will be ensured, happiness will be ensured, material welfare will be ensured. The main problem lies in these two areas.
The Holy Prophet (s.w.a.) says, "I was appointed as Prophet to perfect moral virtues." Also, the Holy Quran says, "He it is Who raised among the inhabitants of Mecca a Messenger from among themselves, who recites to them His communications and purifies them." [The Holy Quran, 62, 2] After mentioning purification in the ayah, the Holy Quran continues, "... and teaches them the Book and the Wisdom." This is a lofty goal: purifying human beings, cleansing hearts, improving commitment of humanity to ethics and saving human beings from moral problems, ethical weaknesses and human passions. This is a goal.
The issue of thinking is also an essential issue and it is not particular to the Prophet of Islam (s.w.a.). All prophets were sent to revive the power of thinking among human beings. The Commander of the Faithful (a.s.) says in a sermon in Nahjul Balaghah, "Then Allah sent His Messengers and series of His prophets towards them to get them to fulfill the pledges of His creation, to recall to them His bounties, to exhort them by preaching, to unveil before them the hidden treasure of wisdom." Prophets were sent to uncover the treasure of wisdom which is hidden in human beings.
Human beings have a great capacity for thinking. When we do not think, when we do not study, when we do not reflect on the divine signs, when we do not reflect on our history, on the different events that have happened to humanity, on the past afflictions and on the causes of great victories that nations have achieved, we deprive ourselves of the spiritual treasure that Allah the Exalted has bestowed on us. "Then Allah sent His Messengers and series of His prophets towards them to get them to fulfill the pledges of His creation, to recall to them His bounties, to exhort them by preaching, to unveil before them the hidden treasure of wisdom." Today humanity needs these two things.
