For he who hates you, he will be cut off.
meaning, `indeed he who hates you, O Muhammad, and he hates what you have come with of guidance, truth, clear proof and manifest light, he is the most cut off, meanest, lowliest person who will not be remembered.
Ibn `Abbas, Mujahid, Sa`id bin Jubayr and Qatadah all said,
"This Ayah was revealed about Al-As bin Wa'il. Whenever the Messenger of Allah would be mentioned (in his presence) he would say,
`Leave him, for indeed he is a man who is cut off having no descendants. So when he dies he will not be remembered.'
Therefore, Allah revealed this Surah."
Shamir bin `Atiyah said,
"This Surah was revealed concerning `Uqbah bin Abi Mu`ayt."
Ibn `Abbas and `Ikrimah have both said,
"This Surah was revealed about Ka`b bin Al-Ashraf and a group of the disbelievers of the Quraysh."
Al-Bazzar recorded that Ibn Abbas said,
"Ka`b bin Al-Ashraf came to Makkah and the Quraysh said to him,
`You are the leader of them (the people). What do you think about this worthless man who is cut off from his people He claims that he is better than us while we are the people of the place of pilgrimage, the people of custodianship (of the Ka`bah), and the people who supply water to the pilgrims.'
He replied, `You all are better than him.'
So Allah revealed, "
إِنَّ شَانِيَكَ هُوَ الاٌّبْتَرُ
(For he who hates you, he will be cut off.)"
This is how Al-Bazzar recorded this incident and its chain of narration is authentic.
It has been reported that Ata' said,
"This Surah was revealed about Abu Lahab when a son of the Messenger of Allah died. Abu Lahab went to the idolators and said,
`Muhammad has been cut off (i.e., from progeny) tonight.'
So concerning this Allah revealed, "
إِنَّ شَانِيَكَ هُوَ الاٌّبْتَرُ
(For he who hates you, he will be cut off.)"
As-Suddi said,
"When the male sons of a man died the people used to say, `He has been cut off.' So, when the sons of the Messenger of Allah died they said, `Muhammad has been cut off.'
Thus, Allah revealed, "
إِنَّ شَانِيَكَ هُوَ الاٌّبْتَرُ
(For he who hates you, he will be cut off.)"
So they thought in their ignorance that if his sons died, his remembrance would be cut off.
Allah forbid! To the contrary, Allah preserved his remembrance for all the world to see, and He obligated all the servants to follow his Law. This will continue for all of time until the Day of Gathering and the coming of the Hereafter. May the blessings of Allah and His peace be upon him forever until the Day of Assembling.
This is the end of the Tafsir of Surah Al-Kawthar, and all praise and blessings are due to Allah
