And do not say regarding (anything) which is (based just on) the false utterances of your tongues, “”This is lawful and this is unlawful,”” so as to forge (a lie) against Allah, those who forge a lie against Allah will certainly not be successful.
Only Allah (SWT) through His messenger makes things lawful and prohibited. No one else has the right to do this, basing his decision on his desire. They may enjoy the unlawful things temporarily but will be punished later. For those who do evil in ignorance but repent and correct themselves, Allah (SWT) is Protectively Forgiving and Merciful.
