Meaning, indeed, the one who dislikes you is the one who is cut off from lineage or from any good.
As mentioned, this verse was revealed to correct the human standards according to the divine ones. For the repute is not through the lineage and the relatives, whereas it is through the value and the effect. Thereof, the Messenger (saws) is not the one who is cut off because his lineage is connected to all his nation’s children. Whereas, the cut off one is that who claimed the Messenger of that.
The remembrance of the Messenger (saws), even after his death, will continue, on the tongues of his followers and in their hearts and souls, through the calling of prayer (Athan) and in every time until Allah (swt) will inherit the earth and whoever is on it. Hence, whenever his name (saws) is mentioned, there is a mention of one of Allah’s (swt) rule, so how it comes that the Messenger is cut off!!!
The Messenger’s repute is connected with the hereafter, Allah (swt) says:
﴾وَرَفَعْنَا لَكَ ذِكْرَكَ ﴿
(And raised high for you your repute.) (Ash-Sharh: 4)
On the Day of Judgement, the Messenger’s (saws) repute will be raised above all the humans from Adam (pbuh) till the Resurrection Day, where all the Prophets (pbut) will refuse to intercede, the one who will accept to hold the intercession is only the Prophet Muhammad (saws). So, his repute is raised high over those who came before him and who comes after him.
We notice that in replying to those who said that the Messenger is cut off, Allah (swt) did not say (No , you are not cut off), rather the reply is: (Indeed, We have granted you, [O Muhammad], al-Kawthar), since the one who is given Al-Kawthar, is never ever cut off.
شَانِئَكَ (your enemy): This indicates that the animosity is directed to him (saws) personally and to his calling to Allah (swt) and the method. They were saying:
﴾ وَقَالُوا لَوْلَا نُزِّلَ هَٰذَا الْقُرْآنُ عَلَىٰ رَجُلٍ مِّنَ الْقَرْيَتَيْنِ عَظِيمٍ﴿
(And they said, “Why was this Qur’an not sent down upon a great man from [one of] the two cities?”) (Az-Zukhruf: 31)
They disliked him because he has come with this great Islamic method and overpowered them with argument and proof, additionally, their attempts to prevent him have all failed, they accused him of being a poet, a magician and a soothsayer, and when they failed to find any faults in the Holy Qur’an they started to disgrace him (swt), but Allah (swt) replied to them by a similar way. This is a general law that the characteristic is connected with the doer, whether exists or not. In other words, whoever dislikes the Messenger of Allah (saws) is cut off in general, not in particular those who claimed that he is cut off because the moral lies in the general meaning, not in the specific reason.
