Allah's message refers to the guidance and teachings that Allah has sent down to humanity through His prophets and messengers, and which are recorded in the Holy Scriptures, such as the Quran, the Bible, and the Torah.
In Islam, the Quran is considered to be the ultimate and final revelation from Allah to humanity, which was revealed to the Prophet Muhammad (peace be upon him) over a period of 23 years. The Quran contains guidance for all aspects of human life, including matters of faith, ethics, morality, social justice, and governance.
Allah's message in the Quran emphasizes the importance of monotheism and the belief in the oneness of Allah. It calls upon human beings to worship Allah alone, and to submit to His will by following His commandments and avoiding sin and evil deeds.
The message of Allah in the Quran also emphasizes the importance of compassion, mercy, and justice.
