"There is no lord worthy of worship except Allah,
Muhammad is the messenger of Allah"
The
Arrival of Islam
In
637 A.D., only five years after the death of the Prophet Muhammad, Arab
Muslims shattered the might of the Iranian Sassanians at the battle of
Qadisiya, and the invaders began to reach into the lands east of Iran. By
the middle of the eighth century, the rising Abbasid Dynasty was able to
subdue the Arab invasion, putting an end to the prolonged struggle. Peace
prevailed under the rule of the caliph Harun al Rashid (785-809) and his
son, and learning flourished in such Central Asian cities as Samarkand. From
the seventh through the ninth centuries, most inhabitants of what is
present-day Afghanistan, Pakistan, southern parts of the former Soviet
Union, and areas of northern India were converted to Sunni Islam.
In the
eighth and ninth centuries ancestors of many of today's Turkic-speaking
Afghans settled in
the Hindu Kush area (partly to obtain better grazing land) and began to
assimilate much of the culture and language of the Pashtun tribes already
present there.
By
the middle of the ninth century, Abbasid rule had faltered, and
semi-independent states began to emerge throughout the empire. In the Hindu
Kush area, three short-lived, local dynasties ascended to power. The best
known of the three, the Samanid, extended its rule from Bukhara as far south
as India and west as Iran. Although Arab Muslim intellectual life still was
centered in Baghdad, Iranian Muslim scholarship, that is, Shia Islam,
predominated in the Samanid areas at this time. By the mid-tenth century,
the Samanid Dynasty had crumbled in the face of attacks from Turkish tribes
to the north and from the Ghaznavids, a rising dynasty to the south.
