Narrated from Sayyiduna Sahl bin Sa’d (may Allah be pleased with him), the Noble Prophet (peace and blessings be upon him) said: The Book of Allah is present among you; black, white, and red, everyone learns it. Learn it before the time comes when people will learn it, but it will not go below their collarbones, and they will straighten its words as an arrow is straightened, but they will seek its reward in this world and will not delay it until the Hereafter.
