Spot on, From what I understand, everything is Halal UNLESS its deemed to be Haram/unlawful under Islamic law
Glad you brought this up as Ive noticed many people on here are too quick to play the Haram card...which is sad to see and pretty off putting if im honest
Asalaam O Alaikum....
Since this is true that there are no such things in this world which absolutely fall either in Haraam or Halaal category. As times change, Muslims lifestyle changes and mankind invents new things and changes take place in collective as well as Individual way of life of Muslims.
For example when Camera was invented many Islamic Scholars around the world termed it as Haraam. But when they saw that the Camera is just an instrument, it can either be used for good purposes or to create Fitnah. When it was thoroughly made clear that it has a good purpose as well, that is when Majority scholars declared it as Halaal and few even up till today decline that a camera takes their picture and still term it as Haraam and they have their own opinions. They are very few.
The Hadith Of Prophet Muhammad (saw) makes it clear for us how to avoid something if we're not sure whether it falls under Halaal or Haraam category or until it is thoroughly proven Halaal.
Narrated An-Nu'man bin Bashir: I heard Allah's Apostle saying,
'Both legal and illegal things are evident but in between them there are doubtful (suspicious) things and most of the people have no knowledge about them. So whoever saves himself from these suspicious things saves his religion and his honor. And whoever indulges in these suspicious things is like a shepherd who grazes (his animals) near the
hima (private pasture) of someone else and at any moment he is liable to get in it. (O people!) Beware! Every king has a
hima and the
hima of Allah on the earth is His illegal (forbidden) things. Beware! There is a piece of flesh in the body if it becomes good (reformed) the whole body becomes good but if it gets spoilt the whole body gets spoilt and that is the heart. (Book
#2, Hadith
#49 Al Bukhari)
The hadith makes it clear that if there is something which is doubtful don't do it or accept it, even if there are chances it could be Halaal because it is said that there is much higher reward for the person who abandoned even what could be Halaal only for the Fear of earning displeasure of Allah (swt) and for no other reason.
This shows the extent of fear of loosing nearness of Allah (swt) for which inshA'Allah the person is rewarded even greater. This is a sign of Sure Faith.
Imam Ghazali says the following:
Prophet (saw) said
"Nobody can be a god fearing man unless he gives up what causes no harm to him for fear of what causes harm."
For instance, such a man does not state all affairs to the people lest he is drawn to back biting or he fears to eat delicious food or drink lest it stimulates passion and lust which drive people to commit unlawful things.
So it It all depends on the level of one's Fear and love of Allah (swt) i.e. Taqwa.
We should not forget that this world is a test and everything in it which makes us attached to it could be a trap and therefore we have to make sure that it is not a trap we're falling for.
Prophet (saw) said
"Sin is heart alluring."
Therefore my conclusion would be that we cannot say whether a Thing is Halaal or a thing is Haraam until proven. Until it is proven, even though it might take years, we should hold our horses and not accept it blindly because of "What if" reason....and that is a blessing as it happens because of Taqwa (Fear and love of Allah (swt))
