What is the evidence for stipulating the acceptance in the Quran and the Prophetic Sunnah?

{ [The angels will be ordered], "Gather those who committed wrong, their kinds, and what they used to worship .... And were saying, "Are we to leave our gods for a mad poet?" }

The Messenger of Allah (may the peace and blessings of Allah be upon him) said, "The guidance and knowledge with which Allah has sent me are like abundant rain which fell on a land. A fertile part of it absorbed the water and brought forth profuse herbage and pasture; and solid ground patches which retained the water by which Allah has benefited people, who drank from it, irrigated their crops and sowed their seeds; and another sandy plane which could neither retain the water nor produce herbage. Such is the similitude of the person who becomes well-versed in the religion of Allah and receives benefit from the Message entrusted to me by Allah, so he himself has learned and taught it to others; such is also the similitude of the person who has stubbornly and ignorantly rejected Allah's Guidance with which I have been sent."
