What lesson did the Prophet Muhammad (saw) teach us through the hadith he narrated about 'Both legal and illegal things'?
      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.
