In his book "Histoire de la Turquie" (1854), Alphonse de Lamartine writes:
If greatness of purpose, smallness of means, and astounding results are the three criteria of human genius, who could dare to compare any great man in modem history with Muhammad? The most famous men created arms, laws and empires only. They founded, if anything at all, no more than material powers, which often crumbled away before their eyes.
This man moved not only armies, legislations, empires, peoples and dynasties, but millions of men in one-third of the then-inhabited world; and more than that he moved the altars, the gods, the religions, the ideas, the beliefs and souls.... His forbearance in victory, his ambition which was entirely devoted to one idea and in no manner striving for an empire, his endless prayers, his mystic conversations with God, his death and his triumph after death-all these attest not to an imposture, but to a firm conviction, which gave him the power to restore a dogma. This dogma was two fold: the unity of God and the immateriality of God; the former telling what God is, the latter telling what God is not; the one overthrowing false gods with the sword, the other starting an idea with the words. Philosopher, orator, apostle, legislator, warrior, conqueror of ideas, restorer of rational beliefs, of a cult without images; the founder of twenty terrestrial empires and of one spiritual empire, that is Muhammad. As regards all standards by which human greatness may be measured, we may well ask, is there any man greater than he.
Who was Lamartine?(wiki)
Alphonse Marie Louis de Prat de Lamartine (21 October 1790 – 28 February 1869) was a French writer, poet and politician who was instrumental in the foundation of the Second Republic.Lamartine is famous for his partly autobiographical poem, "Le lac" ("The Lake"), which describes in retrospect the fervent love shared by a couple from the point of view of the bereaved man. Lamartine was masterly in his use of French poetic forms. Raised a devout Catholic, Lamartine became a pantheist, writing Jocelyn and La Chute d'un ange. He wrote Histoire des Girondins in 1847 in praise of the Girondists.
He worked for the French embassy in Italy from 1825 to 1828. In 1829, he was elected a member of the Académie française. He was elected a deputy in 1833 and was briefly in charge of the government during the turbulence of 1848. He was Minister of Foreign Affairs from 24 February 1848 to 11 May 1848. Due to his great age, Jacques-Charles Dupont de l'Eure, Chairman of the Provisional Government, effectively delegated many of his duties to Lamartine. He was then a member of the Executive Commission, the political body which served as France's joint Head of State.
Lamartine was instrumental in the founding of the Second Republic of France, having met with Republican Deputies and journalists in the Hôtel de Ville to agree on the makeup of its provisional government. Lamartine himself was chosen to declare the Republic in traditional form in the balcony of the Hôtel de Ville.
