Sahl bin Saad al-Saeedi said: The Messenger of Allah صلی اللہ علیہ وسلم one day came out to us while we were reciting the Quran. He said: Praise be to Allah. The Book of Allah is one, and among you are the red, and among you are the white and among you are the black. Recite it before there appear people who will recite it and straighten it as an arrow is straightened. They will get their reward for it in this world and will not get it in the Hereafter.
