Musannaf Ibn Abi Shayba 33:556

Abu Khalid al-Ahmar narrated to us, from ‘Amr ibn Qays, from ‘Ikrimah, from Ibn ‘Abbas: Allah has guaranteed for whoever follows the Qur’an that he will not go astray in the world, nor will he be wretched in the Hereafter. Then he recited: "Whoever follows My guidance will neither go astray nor suffer."
