Means "praiseworthy", derived from Arabic حمد (hamid)
"to praise". This was the name of the prophet who founded the Islamic religion in the 7th century. Since his time, it has been very popular in the Muslim word.
The name was borne by six sultans of the Ottoman Empire (though their names are usually given in the Turkish spelling Mehmet). Another famous bearer was Muhammad ibn Musa al-Khwarizmi, a 9th-century Persian mathematician and scientist who devised algebra.
