Abstract
In this article, under the light of the hadith and the Sunnah the value of the daughters has been dealt with and the opinion that the daughters are second class child has been criticized. Along human history generally the daughters, because of their physical and psychological weakness, have been accepted less important than boys in many societies. When families have sons they have felt themselves happy and lucky. Women who give birth to sons have been respected by their husbands and relatives but who give birth to girls have been denigrated. Before Muhammad (pbuh) the negative behavior against daughters was one of the best characteristic of Meccan people also. According to some researches in this era, also known as pre-Islamic age of ignorance, some daughters have been buried alive. The Holy Prophet Muhammad has recommended to all Muslims to be in good behavior towards to the girls and he was the best example in this issue.
