(39) باب فَضْلِ مَنِ اسْتَبْرَأَ لِدِينِهِ
Narrated An-Nu'man bin Bashir:
I heard Allah's Messenger (ﷺ) saying, 'Both legal and illegal things are evident but in between them there are doubtful (suspicious) things andmost 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 whograzes (his animals) near the Hima (private pasture) of someone else and at any moment he is liable to get in it. (O people!) Beware! Everyking 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.
