الملخص EN

When the holy Qur'an was revealed, and the Arabs conquered the neighboring countries of the Arabian peninsula, the peoples mixed and the tongues mixed, and non-Arabs entered Islam and melted into the Qur'an and Arabic, which allowed the melodies to appear and become more widespread later on their tongues.

which spoiled the significance and distorted the meanings of the wise download, the point that made Arabic scholars feel the need to protect the Qur'an and its language in order to preserve it from slipping, and the result of this was the emergence of grammatical rules controlling the last words, a safety valve for the meanings.

so how was the way to those rules when there was no covenant for Arabic and the Arabs for it ? and how was the grammatical complex ? and what are its controls ?.
