(This is the) Book (the Quran) sent down unto you (O Muhammad SAW), so let not your breast be narrow therefrom, that you warn thereby, and a reminder unto the believers.
[Say (O Muhammad SAW) to these idolaters (pagan Arabs) of your folk:] Follow what has been sent down unto you from your Lord (the Quran and Prophet Muhammad’s Sunnah), and follow not any Auliya’ (protectors and helpers, etc. who order you to associate partners in worship with Allah), besides Him (Allah). Little do you remember!
Chapter 7 Al-‘Ā ̀rāf : Verses 2-3
((This is the) Book (the Qur’an) sent down unto you (O Muhammad)), from your Lord,
(so let not your breast be narrow therefrom,) meaning, having doubt about it according to Mujahid, Qatadah and As-Suddi. It was also said that the meaning here is: `do not hesitate to convey the Qur’an and warn with it,’
(Therefore be patient as did the Messengers of strong will) (46:35). Allah said here,
(that you warn thereby) meaning, `We sent down the Qur’an so that you may warn the disbelievers with it,’
(and a reminder unto the believers). Allah then said to the world,
(Follow what has been sent down unto you from your Lord) meaning, follow and imitate the unlettered Prophet , who brought you a Book that was revealed for you, from the Lord and master of everything.
(and follow not any Awliya’, besides Him (Allah)) meaning, do not disregard what the Messenger brought you and follow something else, for in this case, you will be deviating from Allah’s judgment to the decision of someone else. Allah’s statement,
(Little do you remember!) is similar to,
(And most of mankind will not believe even if you desire it eagerly)(12:103), and;
(And if you obey most of those on the earth, they will mislead you far away from Allah’s path)(6:116), and,
(And most of them believe not in Allah except that they attribute partners unto Him)(12:106).
