The change from persecuted preacher to head of state can reasonably raise questions about motive. But the whole record does not fit a man who invented revelation mainly for power, wealth, or status; it fits a prophet whose mission eventually required public leadership and whose life repeatedly imposed costs upon him.

Why the suspicion seems plausible

The skeptical argument has real force at the level of appearance. Prophet Muhammad (PBUH) began as a preacher with no army, then became the leader of a growing community, a military commander, and the ruler of much of Arabia. His household included several wives, and some revelations addressed matters connected with his domestic and political life. A critic may therefore ask whether "revelation" simply gave divine authority to personal preferences and political decisions.

That possibility should not be dismissed by saying that every successful religious leader must be sincere. A talented organizer can sincerely believe his own message, and personal sincerity by itself does not prove prophethood. The question is whether the wider evidence is best explained by deliberate fabrication for worldly advantage.

What his career actually cost him

At the beginning, the proposed path to power was an astonishingly poor strategy. He endured mockery, persecution, a social boycott, and the deaths of close supporters. The leading men of Makkah offered him wealth, status, and leadership if he would abandon his preaching. He refused, while having no visible prospect of political success.

Even after authority came, his personal life was marked by restraint rather than royal luxury. Authentic reports describe long periods in which no cooking fire was lit in his homes, and after his death his property was not treated as an inheritance for his family.

"We, the community of prophets, are not inherited from; what we leave is charity."

Sahih al-Bukhari; Sahih Muslim

He did benefit from legitimate authority as a ruler, including public resources administered for the community. But he did not establish a hereditary monarchy, accumulate a private fortune, or leave his family a royal estate. His relatives and companions also suffered hardship, exile, and death. A theory of calculated self-enrichment must explain why the mission involved so much danger and so little personal security.

The verses that appear most self-serving

Quran 33:50 grants the Prophet (PBUH) permissions concerning marriage that were not generally available to other believers. Read superficially, this can look like a private privilege disguised as revelation. Classical scholars did not deny that the ruling was specific to him. They understood it within the responsibilities of his prophetic household, social alliances, and the distinction between prophetic law and ordinary law. It remains a passage that requires explanation, not concealment.

"O Prophet, We have made lawful for you your wives to whom you have given their bridal gifts..."

Quran 33:50

Yet the Quran also records revelation correcting him in matters where a fabricated scripture would naturally protect his image:

"O Prophet, why do you prohibit what Allah has made lawful for you, seeking the approval of your wives? And Allah is Forgiving, Merciful."

Quran 66:1

The Quran also preserves rebukes and difficult passages about his decisions. Such material does not prove prophethood by itself, but it cuts against the idea of a text designed simply as a ruler's shield.

What the argument establishes

The motive objection establishes that some rulings require careful study and that outward political success cannot by itself prove revelation. It does not establish that Muhammad (PBUH) fabricated Islam for gain. His early losses, later sacrifices, moral teaching, modest lifestyle, public corrections, and refusal to turn prophethood into inherited wealth make deliberate worldly fraud a poor overall explanation.
