In reality...
In reality, the doubtful acts are the sanctuary of the prohibited acts and thus, we must stay away from these since their force and power is just like electricity which is so great such that if a person was to get too near this electricity, it would not only pull the person close, but it would also burn him!
In our traditions, there is a good explanation which has been given that states, “Do not enter into the private property of other people otherwise you may be pulled towards usurpation.” There are many people who have been pulled towards drug addiction in their lives and in the beginning we see that they give the excuse that they are smoking just to pass time and for pleasure, however it reaches a point where they are completely dependent on such things.
The nineteenth characteristic of a true believer is that he gives a great deal to other people. As we know, the word “a lot” is a relative term. For example, if in order to build a hospital which is needed in a society, a rich person (who has millions of dollars) gives $100,000.00 then this amount may be - in relation to his amount of wealth - something very small.
However if a person who is not well off gives $1,000.00 (which may be a large portion of his savings), then everyone would congratulate him. Therefore, giving gifts and charity are things which are relative. During the battle of Tabuk, the Prophet (S) asked the people to prepare the Muslim troops for battle and everyone helped quite a bit.
Amongst those who gave in the way of Islam, there was a simple worker who in order to help the Muslim army - worked an extra night and whatever earnings he gained on that night, he presented to the Prophet (S).
