Why Will Allah Not Accept The Deeds of The Kuffar?

 Answer: 

Allah created the creation for His worship commanded them to obey Him. He also sent Messengers giving glad tidings and warning; who illuminated the right path for the people, made them understand the proof and they clarified the goal. To whomever the truth is clear and evident but is spite of that he deliberately prefers renuciation and denial, without being under any coercion or insanity, such a person deserves punishment for his deeds.

On the Day of Resurrection, Allah will make His entire creatures stand on the plain of judgment and He will take their account in the varieties of their nationalities, colour and religion. While narrating the situation of the Kuffar on the Day of Resurrection,

And (remember) the Day when We will call them, and say; Where are My (so-called) partners whom you used to assert.´´ (Surah Al-Qasas: 62)

Yes, where are the partners whom you used to worship, exalt and seek nearness to; whom you claimed were gods alongside Allah? Where will they be on that day? Can they benefit or save you from the punishment?

Allah says,

And (remember) the Day (Allah) will call to them, and say: ´´What answer gave you to the Messengers.´´ (Surah Al-Qasas: 65)

The Mighty and Exalted also says,

But as for him whose balance (of good deeds) will be light, he will have his home in Hawiyah (pit, i.e. Hell). and what will make know what it is? (It is) a hot blazing Fire.´´ (Surah Al-Qari´ah: 8-11)

Whose balance is lighter and more trivial than that of a kafir?

Allah also says,

Andthose whose scale (of good deeds) are light, they are those who lose their own selves, in Hell will they abide. The Fire will burn their faves, and therein they will grin, with displaced lips (disfigured). Were not My Verses (this Qur´an) recited to you, and then you used to deny them. (Surah Al-Mu´minun: 103-105)
