All praises and thanks belong to Allah. I bear witness that there no deity worthy of worship except Allah Alone with no partner and he begets not nor was he begotten.

And I bear witness that our master and Prophet Muhammad is His slave and final messenger.

May peace and blessings be upon him, his household, companions and those who follow him in truth up until the day of reckoning.

To proceed, the Shari'ah that Allah commanded to be the only way of for Judgement is Hanafiyyah, the religion of Prophet Ibraheem (Abraham) (peace be upon him).

Allah said, " Truly, the religion with Allah is Islam." {Qur'an 3:19}

Allah said, " Do they seek other than the religion of Allah (the true Islamic Monotheism- worshipping none but Allah alone), while to Him submitted all creatures in the heavens and the earth, willingly or unwillingly, And to Him shall they all be returned. " {Qur'an 2:83}

Allah said, " And whoever seek a religion other than Islam, it will never be accepted of him, and in the hereafter he will be one of the losers." {Qur'an 3:85}

Allah said, " And who turns away from the religion of Ibraheem (Abraham) (i.e. Islamic Monotheism) except him who befools himself? {Qur'an 2:130}

Allah said, " Or have they partners with Allah (false gods) who have instituted for them a religion which Allah has not ordained? " {Qur'an 42:21}
There are many verses to the same effect.

You've failed to state what Allah commanded, which is "Do Allah's Will", which I would claim is the following:

"'Love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind' and 'Love your neighbors and your enemies even moreso.'"

Those who do not do this are most definitely worshipping shaitan, in my opinion.

What's your's?
