“So do not call on any other god beside Allah lest you become of those who will be punished, and warn your nearest kinsmen….”
(Al Qur’ān – 26:213-14)
This statement doesn’t mean that there was any danger that the Messenger ﷺ was, indeed, going to associate aught with God in His Divinity and that he needed to be so prevented by means of admonition, from doing so. Rather, the object of the statement was to warn the unbelievers and polytheists.
What is being said here can be summarised as follows: The Message of the Qur’ān is based on pure Truth which has been revealed by the Sovereign of the universe and which has been made immune against every kind of satanic interpolation. Therefore, there is no possibility of undue favour to anyone.
Among God’s creatures, it is the Messenger whom God loves the most. Notwithstanding this, it is also being made clear that even if he were to deviate, even just a little bit, from the True Path and invoke any deity other than God, he too would not escape God’s punishment. If such is the case with even the Blessed Messenger, who else can ever hope to escape God’s wrath after committing shirk (polytheism)?
Just as there is no special consideration or undue favour even for the most exalted person, i.e. the Blessed Messenger in matters pertaining to God’s Religion, there can be no question of any undue favour being shown to the Messenger’s family or to those whom he held dear.
