In a hadeeth Prophet a s has said: Whatever I declare halal it is halal till qiyamat and whatever declare haram it is haram till qiyamat
I have a question regarding the Quran. I know very well that the Quran was sent to mankind of all times so that the people of the time of the Prophet saws had a guidance just as it is a guidance for us in this era. But is this ever mentioned in a hadith or verse in the Quran?
