Concept:The central message of Prophet Muhammad’s (SAW) mission in Makkah was the call to pure monotheism, known as Tawhid.
Explanation:The Qur’an instructed the Prophet (SAW) to proclaim the oneness of Allah and to worship Him alone.
He was commanded to reject all forms of idol worship and to avoid associating partners with Allah.
This message was the foundation of his da’awah in Makkah, as the society was deeply entrenched in polytheism.
The Prophet (SAW) also warned the unbelievers about divine punishment, but this warning was secondary to the central call of Tawhid.
Thus, the essence of his early preaching was not business, brotherhood, or punishment alone, but the absolute unity of Allah.
Answer:The unity of Allah.
