In Islamic Writings, Muhammad Was White

Because Arabs and other Muslims often have darker skin than Europeans, opposition to the spread of Islam and negative opinions about Islam are often called "racism", even though Islam is an ideology and a religion, not a race.  Its adherents, like those of Christianity, come in all colors.  And as James Wood points out, in Islamic sources such as the ahadith, the founder of Islam is called "white".  (In Arabic, hadith is singular and ahadith is plural.)

According to other ahadith, Muhammad also owned and traded slaves, including black slaves, and preached from a pulpit built by a slave.
