Please define for me the precise message which Allah Most High commanded all the Prophets to preach?
In the Name of Allah, the Most Merciful and Compassionate
All Prophets and Messengers (may Allah bless them and give them peace), from Adam to Muhammad, were sent with a message of pure Divine monotheism. This message is encapsulated in the statement La ilaha ill Allah – There is none worthy of worship other than Allah.
They were also sent with the general message of obedience to the limits of Allah Most High, even though the specifics of the Sacred law differed between them.
Allah Most High says, “We never sent a messenger before you ˹O Prophet˺ without revealing to him: “There is no god ˹worthy of worship˺ except Me, so worship Me ˹alone˺.” [Qur’an; 21:25]
The message of Divine Oneness
Tawhid or Divine Oneness is the central teaching of all Prophets and Messengers.
Some details of the Sacred Law differed between the Prophets and Messengers under their people and circumstances.
Despite this, some core rulings remained the same throughout—for example, the prohibition of unjust killing.
Allah Most High says, “Relate to them in truth ˹O Prophet˺ the story of Adam’s two sons—how each offered a sacrifice: Abel’s offering was accepted while Cain’s was not. So Cain threatened, “I will kill you!” His brother replied, “Allah only accepts ˹the offering˺ of the sincerely devout. – If you raise your hand to kill me, I will not raise mine to kill you because I fear Allah—the Lord of all worlds. – I want to let you bear your sin against me along with your other sins, then you will be one of those destined to the Fire. And that is the reward of the wrongdoers.” – Yet Cain convinced himself to kill his brother, so he killed him—becoming a loser…
…That is why We ordained for the Children of Israel that whoever takes a life – unless as a punishment for murder or mischief in the land—it will be as if they killed all of humanity; and whoever saves a life, it will be as if they saved all of humanity. ˹Although˺ Our messengers already came to them with clear proofs, many of them still transgressed afterward through the land.” [Qur’an; 05:27-52]
Hope this helps
