Judging by laws other than those revealed by Allah
Is one who judges by other than Allah’s revealed Law considered a Muslim, or a disbeliever, guilty of major Kufr (major disbelief)?
What about the acceptance of their deeds?
Allah (Exalted be He) says (what means):
And whosoever does not judge by what Allâh has revealed, such are the Kâfirûn (i.e. disbelievers of a lesser degree as they do not act on Allâh’s Laws).
And whosoever does not judge by that which Allâh has revealed, such are the Zâlimûn (polytheists and wrong-doers - of a lesser degree).
Allah also says:
And whosoever does not judge by what Allâh has revealed (then) such (people) are the Fâsiqûn [the rebellious i.e. disobedient (of a lesser degree) to Allâh].
If those mentioned in these Ayahs deem that as lawful and permissible, they will be guilty of major disbelief, major wrong and major disobedience, which takes them out of the fold of Islam. If they do so for a bribe or any other purpose, while believing in the prohibition of doing so, they are sinful, and are considered disbelievers, guilty of minor disbelief; wrongdoers, guilty of minor wrong; and disobedient, guilty of minor disobedience, yet that does not take them out of Islam, according to the exegetes of the Qur’an in their interpretation of the previously mentioned Ayahs.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
