Raising children is a great mission in this life and should hold a place of high priority. Spending on one's family to cover their essential needs is more rewarding than spending in any other cause.
The Prophet (s.a.w.) said: {When the human being dies, his/her deeds will come to an end except three kinds: Sadaqah Jariah (continuous charity), beneficial knowledge, and a good child that will pray for him/her.} (Muslim).
The Prophet (s.a.w.) also said: {A dinar (currency unit from gold) you spend in the sake of Allah, a dinar you spend to free a slave, a dinar you donate to the poor, and a dinar you spend on your family, the most rewarding among them is the dinar that you spend on your family.} (Muslim).
The Prophet (s.a.w.) also said: {The best dinar a man spends is a dinar he spends on his family, a dinar he spends on his animal, and a dinar he spends on his companions in the sake of Allah.} (Muslim).
Whoever offers or loses three or two children in the sake of Allah, they will protect him/her from the Hell fire, as the Prophet (s.a.w.) told us.
The Prophet (s.a.w.) said: {When three children die for a Muslim the Hell fire will not touch him except for fulfilling the oath.} (Muslim). The oath fulfillment refers to the Qur'anic verse that declares that every human being will touch the Hell fire.
Allah (s.w.t.) said: {{There is not one of you but shall approach it (Hell). That is a fixed ordinance from Allah. Then We shall rescue those who kept from evil, and leave the evildoers crouching in it.}} [Al-Qur'an: Maryam (19:71-72)].
Abu Sa`id Al-Khudri narrated: {A woman from Al-Ansar came to the Messenger of Allah (s.a.w.) and said: "The men have got all your speeches, so, make a day for us on which we come to you to teach us from what Allah taught you." He said: "Meet on such and such day". They met, and he came to them and taught them from what Allah taught him, and then said: "Every woman among you offers (in the sake of Allah) three children they will be protection for her from the Hell fire." A woman asked: "How about two?". The Messenger of Allah (s.a.w.) said: "And two".} (Al-Bukhari and Muslim).
Raising children, especially girls, is very important in Islam. It is a good way to seek more rewards in the hereafter. Many people tend to discriminate between their sons and daughters, and tend to favor the boys. The Prophet (s.a.w.) emphasized the reward of raising daughters and showed that it is a protection from the Hell fire.
Imam Al-Bukhari narrated these four Hadiths in his book Al-Adab Al-Mufrad (not to be confused with his famous book of Hadith called Sahih Al-Bukhari):
The Prophet (s.a.w.) said: {Whoever had three daughters and was patient on raising them, and clothed them from his substance, they would be a protection for him from the Hell fire.}
The Prophet (s.a.w.) also said: {Any Muslim has two daughters, and be a good companion to them, will enter Heaven because of them.}
Jabir Ibn `Abdillah narrated: {The Messenger of Allah (s.a.w.) "Whoever has three daughters that he provides a dwelling for, supports, and has mercy on, Heaven is his guaranteed reward." A man asked: "How about two?". The Messenger of Allah (s.a.w.) said: "And two".}
The Prophet (s.a.w.) said: {Whoever has three daughters or three sisters and supports them will enter Heaven.}
