Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) narrates: The Prophet (peace and blessings of Allah be upon him) came to us while we were reciting (the Qur’an). The Prophet (peace and blessings of Allah be upon him) said: All praise and thanks are due to Allah alone. The Book of Allah is one. Among you are red, white, and black people. You should continue to recite it before there come people who will recite it and assign to it a price as is assigned to a portion.
