Those who Revert to Disbelief (Surah Al-An'am 6:71)

The Parable of Those Who Revert to Disbelief After Faith and Good Deeds

As-Suddi said, "Some idolators said to some Muslims, `Follow us and abandon the religion of Muhammad.' Allah sent down the revelation,

Say: "Shall we invoke others besides Allah, that can do us neither good nor harm, and shall we turn on our heels...'' by reverting to disbelief,

Like one whom the Shayatin (devils) have made to go astray (wandering) through the land, refers to ghouls,

calling him by his name, his father's and his grandfather's names. So he follows the devils' call thinking that it is a path of guidance, but by the morning he will find himself destroyed and perhaps they eat him. The Jinns will then let him wander in a wasteland where he will die of thirst. This is the example of those who follow the false gods that are being worshipped instead of Allah, Most Honored. Ibn Jarir also recorded this. Allah said,

And whomsoever Allah guides, for him there will be none to misguide him. [Surah Az-Zumar 39], and,

If you covet for their guidance, then verily Allah guides not those whom He makes to go astray. And they will have no helpers. [Surah Al-Isra’ 17]

Allah's statement,

and we have been commanded to submit to the Lord of all that exists,   means, we were commanded to worship Allah in sincerity to Him alone, without partners.
