Anas (RadiyAllahu anhu) reported: The Prophet (Sallellahu alaihi wa sallam) said: "Whoever supports two girls till they attain maturity, he and I will come on the Day of Resurrection like this". Messenger of Allah (s.a.w.s.) joined his fingers illustrating this."
In the pre-Islamic era, Arabs were greatly dejected and showed resentment on the birth of a daughter, which in fact reflected the status of women in society, In order to give them their rightful place in the society, Islam taught its followers to recognize their legitimate rights. Among the injunctions which were issued in this behalf, the most important was that their proper upbringing, education and training were made a means to attain Jannah so that people did not only feel joy over the birth of sons but also felt pleasure on the birth of daughters. In this respect, Islam is the first religion which has not only ensured protection of their rights but also made full arrangements for their respect and prestige in society. For instance, they have been prohibited from having close contacts with men and for this purpose restriction of the veil has been imposed on them. Islam has emancipated them from the obligation of earning their own livelihood so that they are safe from the malicious eyes of evil-minded, and secure from the sexual lust of men, the way it is happening with women who are working side by side with men in the West. But it is a curse indeed that due to intellectual immaturity and evil trends, this freedom of women, which has disgraced and robbed them of the virtues of a chaste life, is liked by many people and they are trying that Muslim women should also imitate the style of western women. To the people of such crooked thinking, the Islamic teachings, which ensure the honour and chastity of women, appear to be the yoke of slavery and they want to release women from it.
Further Ahadith stress this point in detail:
Narrated Aisha (r.ah): A lady along with her two daughters came to me asking (for some alms), but she found nothing with me except one date which I gave to her and she divided it between her two daughters, and did not eat anything herself, and then she got up and went away. Then the Prophet came in and I informed him about this story. He said, "Whoever is put to trial by these daughters and he treats them generously (with benevolence) then these daughters will act as a shield for him from Hell-Fire."
[Bukhari, Book 24, Hadith 499]
Narrated Abu Sa'id al-Khudri (radiyAllahu anhu): The Prophet (sallellahu alaihi wa sallam) said: "If anyone cares for three daughters, disciplines them, marries them, and does good to them, he will go to Paradise."
[Abu Dawud/ Book 41/ Hadith 5128]
