Truthfulness is something which everyone knows is important, but yet it is one of the most difficult virtues to make into a habit.

How many times do we lie in a day. Sometimes to avoid people or responsibilities, sometimes to get out of trouble, or sometimes just to make ourselves look big, and to get attention.

There should never be any reason to avoid the truth. If you are honest in your dealings with people, if you have nothing to hide, then you should be able to say the truth without fear.

Qur'an also tells us to tell the truth, and not to cover it with lies.

2:42: And cover not Truth with falsehood, nor conceal the Truth when you know (what it is).

further more, our Prophet (S) has explained to us,

If you make the habit of lying, then you will lie very often without realising. You will lie to your family, your friends and everybody you meet. Then one day you will be caught out because you will have trapped yourself in a corner, and there will be no escape.

Also if you make a habit of lying you will start doing other things which are even worse. One evil leads you to another.
