What was the first major civilization to practice Islam?

Answer 1

The Sassanid Empire or Sasanian Empire. Along with the Byzantine Empire, the Sassanid Empire was recognized as one of the two main powers in Western Asia and Europe for a period of more than 400 years.

During its 400-year existence, the Sassanid Empire encompassed all of today's Iran, Afghanistan, Iraq, Syria, the Caucasus (Armenia, Georgia, Azerbaijan and Dagestan), southwestern Central Asia, most of Turkey, some coastal parts of the Arabian Peninsula, the Persian Gulf area, and parts of southwestern Pakistan.

In many ways the Sassanid period witnessed the highest achievement of ancient Persian civilization, and constituted the last great Iranian empire before joining the Islamic state and the adoption of Islam.

Answer 2

AnswerIt depends on how you define Islam. Islam is an Arabic word that means submission to God, the Creator, the one and only one God with no partner, no son, no companion, and no associate.

Accordingly, in this universal sense of Islam, the first one who practiced Islam is the first created man: Adam

However, if you mean Islam per Quran revelation by Allah (God in English) to prophet Muhammad through the angel Gabriel, then the first one who practiced Islam is prophet Muhammad.

AnswerIt depends on who you're asking. Muslims believe the first practitioner of Islam was Prophet Abraham (pbuh). However, non-muslims generally stated that Prophet Muhammad (pbuh) was the first.
