'Abd al-Muttalib ibn Hashim, was born in Mecca around 570 AD after the death of his father, 'Abd Allah. Muhammad was at first under the care of his paternal grandfather, 'Abd al-Muttalib. Because the climate of
Mecca was considered to be unhealthful, he was given as an infant to a wet nurse from a nomadic tribe and spent some time in the desert. At six, he lost his mother, Aminah of the clan of Zuhra, and at eight his grandfather. Though his grandfather had been head of the prestigious

The poverty and misfortunes of his early life doubtless made him aware of tensions in Meccan society. Mecca, inhabited by the tribe of Quraysh to which the Hashim clan
