«كل قسم قسم في الجاهلية فهو على ما قسم وكل قسم أدركه الإسلام فإنه على قسم الإسلام»
The Prophet (peace and blessings be upon him) said:
"Every division that was made in the time of ignorance (Jahiliyyah) shall remain as it was divided, and every division that Islam has reached shall be according to the division of Islam."
