The Punishment of the Deniers and the Description of the Qur'an
Allah says,
إن الذين يلحدون في آياتنا ﻻ
Verily, Yulhiduna Fi Our Ayat,
Ibn Abbas said,
"Al-Ilhad means putting words in their improper places.''
Qatadah and others said,
"It means disbelief and obstinate behavior.''
ﻻ
يخفون علينا
are not hidden from Us.
This is a stern warning and dire threat, stating that He, may He be exalted, knows who denies His signs, Names and attributes, and He will punish them for that.
He says:
أفمن يلقى في النار خير أم من يٲتي آمنا يوم القيامة
Is he who is cast into the Fire better or he who comes secure on the Day of Resurrection?
means, are these two equal?
They are not equal.
Then Allah warns the disbelievers:
اعملوا ما شيتم
Do what you will.
Mujahid, Ad-Dahhak and `Ata' Al-Khurasani said that
اعملوا ما شيتم
(Do what you will), is a threat. Meaning, `do what you will of good or evil, for He knows and sees all that you do.'
He says:
إنه بما تعملون بصير
Verily, He is All-Seer of what you do
