Calling Haram & Halal, and Quran

First of all study the meanings of Halal and Haram here;

حلال 

حرام

Many Muslims try to use these big words, frequently ,
 without knowledge.

Let's see what Quran says in this regard.

10:59	Say, `Have you ever considered that ALLAH has sent down provision for you, then you make some of it unlawful and some lawful ? Say, `Has ALLAH permitted you that, or do you invent lies against ALLAH ?'
10:60	What think those who invent lies against ALLAH of the Day of Resurrection ? Surely, ALLAH is Gracious towards mankind, but most of them are not thankful.

16:116

And say not - because of the falsehood which your tongues utter - `This is lawful, and this is unlawful,' so as to be of those who forge lies against ALLAH. Surely, those who forge lies against ALLAH do not prosper.

7:31	O children of Adam ! take your adornment at every time and place of worship, and eat and drink, but be not immoderate; surely, HE does not love those who are immoderate.
7:32	Say, `Who has forbidden the adornment of ALLAH which HE has produced for HIS servants and the good things of HIS providing ?' Say, `They are for the believers in the present life and will be exclusively for them on the Day of Resurrection.' Thus do WE explain the Signs for a people who have knowledge.
7:33	Say, `My Lord has only forbidden indecencies, open or secret and sin and wrongful transgression and that you associate with ALLAH that for which HE has sent down no authority, and that you say of ALLAH what you know not.'
