Imaan
If someone says haram thing halal or halal thing haram …does it came out of the fold of islam??
Or if someone says haram thing right or halal thing wrong..does he become kaafir?
How did muslim become kaafir?
Answer
Wa’alaykum as Salām wa rahmatullāhi wa barakātuhu,
In principle, if something has clearly and explicitly been deemed Ḥalāl by way of the Qur’ān (word of Allāh) or Aḥādīth (prophetic traditions), then a person who declares it Ḥarām, and believes such, has committed blasphemy and should repent and turn back to the fold of Islām. The same ruling applies vice versa.
One should refrain from declaring anything as Ḥalāl or Ḥarām, and to rather seek such rulings from the upright religious scholars.
