Very nice topic.
I have compiled a list of Ahadees from various websites related to kids.
It is a famous Tradition of the Prophet (PBUH) that acquisition of knowledge is a must for every Muslim boy and girl. Another Hadith says, “The best of you is one who gives a good education (intellectual and moral) to his children”. Another Hadith lays stress on education of daughters. The Prophet (PBUH) once said, “He who provides good upbringing to 3 daughters shall go to Paradise”. A man asked, “what if one has only two daughters”. “He also shall go to Paradise”. Another man asked, “and what if one has only one daughter?” “He too”, replied the Prophet (PBUH). Once a Bedouin saw the Prophet kissing a small kid. Out of wonder he said, “I have eight children but I never kiss them”. The Prophet remarked, “What can I do if Allah has taken away love and compassion from your heart”. A Hadith says, “It is better for parents to leave their children well provided (financially) than to leave them in poverty”. Messenger of Allah (Peace and blessings of Allah be upon him) used to give his Salaam (greetings) to children and would tell his companions (Sahaba): "I give my Salaam to children and respect them, and Muslims should follow my behavior and always be warm and loving with children." Messenger of Allah (Peace and blessings of Allah be upon him) used to speak about children - boys and girls - and Say: "O Muslims, O fathers and mothers, O my followers, be kind and compassionate towards children, for someone who is not kind to children has no place amongst the Muslims." Messenger of Allah (Peace and blessings of Allah be upon him) said: A virtuous child is a fragrant flower from the flowers of Heaven. Messenger of Allah (Peace and blessings of Allah be upon him) said: Be kind to your children, and excel in this kindness. Messenger of Allah (Peace and blessings of Allah be upon him) said: Have your children to learn swimming and shooting. Messenger of Allah (Peace and blessings of Allah be upon him) said: Train your children in three things: The love of your Prophet, to love the Ahlul Bayt, and the recitation of Noble Qur'an. Messenger of Allah (Peace and blessings of Allah be upon him) said: When your children are grown up to seven years, teach them the prayers, and when they are ten years old, seriously admonish them for it (in order that they establish prayers); and separate their sleeping beds from each other. Messenger of Allah (Peace and blessings of Allah be upon him) said: The child is the master for seven years and a slave for seven years and a vizier for seven years; so if he builds a good character within 21 years, well and good, otherwise leave him alone because you have discharge your responsibility before Allah. Messenger of Allah (Peace and blessings of Allah be upon him) said: Among the rights of the child over the parent are three: To give him a good name, to teach him to write and to marry him when he comes of age. Messenger of Allah (Peace and blessings of Allah be upon him) said: When a person's son matures and he has the financial ability to marry him but does not do so, the boy will commit sin and the sin will be on the father.
JazakAllah Khair ...
