His mother will be Hawiyah.
It has been said that this means he will be falling and tumbling headfirst into the fire of Hell, and the expression `his mother' has been used to refer to his brain (as it is the mother of his head).
A statement similar to this has been reported from Ibn Abbas, Ikrimah, Abu Salih and Qatadah.
Qatadah said,
"He will fall into the Hellfire on his head."
Abu Salih made a similar statement when he said,
"They will fall into the Fire on their heads."
It has also been said that it means his mother that he will return to and end up with in the Hereafter will be Hawiyah, which is one of the names of the Hellfire.
Ibn Jarir said,
"Al-Hawiyah is only called his mother because he will have no other abode except for it."
Ibn Zayd said,
"Al-Hawiyah is the Fire, and it will be his mother and his abode to which he will return, and where he will be settled."
Then he recited the Ayah,
وَمَأْوَاهُمُ النَّار
(Their abode will be the Fire.) (3;151)
Ibn Abi Hatim said that it has been narrated from Qatadah that he said,
"It is the Fire, and it is their abode."
Thus, Allah says in explaining the meaning of Al-Hawiyah,
وَمَا أَدْرَاكَ مَا هِيَهْ
