All religions are based on the same basic principles and they emphasize the same realities. Each Prophet that was sent by Allah acted as if he was the continuation and complement of the previous prophet, repeated the message of his predecessor(s), completed it based on the situation and conditions, clarified the issues that needed explanations, renewed the issues that needed to be renovated and concentrated on the same issues in terms of basic disciplines – in compliance with the conditions of that period and the needs of that time period. These issues of oneness, prophethood, resurrection after death and worship were the primary issues of all prophets. Yes, the principles mentioned above formed the essence of the message of all prophets and apostles with some differences in style, words and attitudes.
The message of the Quran is the continuation of the revelation that began with Hz. Adam (as), the first man and prophet. For, the essence of all religions before Allah is the same: ISLAM.
The prophets that were sent in different eras and places did not reject one another; Hz. Muhammad (pbuh) did not reject any of them, either.
“The Messenger believeth in what hath been revealed to him from his Lord, as do the men of faith. Each one (of them) believeth in Allah, His angels, His books, and His Messengers “We make no distinction (they say) between one and another of His Messengers.” And they say: “We hear and we obey; (We seek) Thy forgiveness, Our Lord, and to Thee is the end of all journeys.” (al-Baqara, 2/285)
“Say: “We believe in Allah, and in what has been revealed to us and what was revealed to Abraham, Isma`il, Isaac, Jacob, and the Tribes, and in (the Books) given to Moses, Jesus, and the Prophets, from their Lord; we make no distinction between one and another among them, and to Allah do we bow our will (in Islam).”(Aal-i Imran, 3/84)
On the contrary, Hz. Muhammad (pbuh) is like the continuation and complement of all of the previous prophets. However, there is a difference; he is the last prophet; no prophet will come after him; therefore, he is the one that rendered the Divine Message have a universal dimension.
Allah, who created man, who knows him with all his details and who meet his needs, sent His message to people in every era and ended it with Hz. Muhammad (pbuh). Thus, there will be no prophets after him; there will not be any change in revelation; and people will act upon the last revelation.
“..This day have I perfected your religion for you, completed my favor upon you, and have chosen for you Islam as your religion…” (al-Maida, 5/3)
“If anyone desires a religion other than Islam (submission to Allah) never will it be accepted of him; and in the Hereafter he will be in the ranks of those who have lost. (all spiritual good)..” (Aal-i Imran, 3/85)
The religion of Islam contains all of the principles that make man materially and spiritually perfect and that ensure his happiness and salvation. Islam leads individuals and communities that follow it to happiness from grace and to perfection from happiness. It gives great importance to the protection of life. It punishes severely those who try to harm the peace in the community. It orders unity, grants and solidarity. It protects social life from anarchy and terror.
Islam presents high ethics to people and makes them benefit from it with all aspects. All of its issues have thousands of benefits, and cures for material and spiritual diseases. The religion of Islam is based on knowledge and wisdom; thus, he leads sane people to good deeds and happiness by making them use their own will. It regards ignorance as the biggest enemy; it leads people to meditation. It is necessary to take into consideration the state of the world before and after the Era of Bliss in order to understand what a great mercy the religion of Islam is for the humanity.
Before Islam, the whole world was under the oppression of ignorance and aberration, terror and anarchy. This savagery and terror that affected the world deeply also impressed the Arabian Peninsula. People used to be proud of burying their daughters. They believed in superstitions, worshipped the idols that they made by their hands and asked their help.
In that dark period, the light of the Quran rose like the sun from a corner of the Arabian Peninsula. It broke into pieces the most intense layers of unbelief and oppression. It dazzled the eyes with its lofty manifestation, cleaned the spirits with its grace and guidance, brightened the minds and enlightened the consciences. It removed polytheism and placed oneness into the hearts. It removed oppression and established justice. It removed hatred and enmity from the hearts and placed love, compassion and mercy into the hearts.
This effect of the Quran is not limited to the Era of Bliss only. Any nation that accepted Islam and practiced it after that made progress and developed in science, trade and business, serving as examples for other nations. The brightest examples are the civilizations of Andalusia, Seljuks and Ottomans. Source: tellmeaboutislam.com
