Mohammed had a message given to him by the Angel Gabriel. But I cann't find the a real new core of this message on the internet. So who can tell me what his core message was and was it really new or just updating the moral?
The message answers some of the fundamental questions about life. Wahiduddin Khan has aptly put:
Every book has its objective and the objective of the Quran is to make man aware of the Creation plan of God. That is, to tell man why God created this world; what the purpose is of settling man on earth; what is required from man in his pre-death life span, and what he is going to confront after death. The Quran and the Creation Plan of God
The purpose in mentioned in Chapter 67
He created death and life so that He might test you, and find out which of you is best in conduct. 67:2
The requirements to succeed in the test are mentioned in the Chapter 103.
I swear by the passage of time, that man is surely in a state of loss, except for those who believe and do good deeds and exhort one another to hold fast to the Truth, and who exhort one another to stead-fastness. 103:1-3
The outcome of this trial is mentioned many times in the Quran.
Give the good news to those who believe and do good works, that they will have Gardens through which rivers flow 2:25
The is the core message and this message has always been the same.
