And We relate to you-O Prophet-from the reports of the messengers who were before you, all what you need of it from what firms your heart for the standing with the burdens of the message, and there has surely come to you in this Surah and what it contained of reports, a clarification of the truth which you are upon, and there has come to you therein an exhortation by which the disbelievers refrain, and a reminder by which the believers in Allah and His messengers remember.
