Equality between Children

Q: I've got two sons. They're toddlers. 

My elder son received alot of money as a gift when he was a baby while the second one didn't receive as much. I was thinking of converting their cash to gold. Will it be okay for me to give money to add only to the younger one so I can get the same amount of gold for each child or will it be unfair to the older child? 

We will not inform them of this when they are older.

Q: Should a parent be equal to all of their children in terms of finance and gifts? 

For example: There are 4 brothers. No. 1 is a doctor, set up by the father but paid back. No. 2 is in the business with his father as a partner, also paid back. No. 3 is still studying. No. 4 is an aalim and recently started working in the business. The father wants to set no. 4 up eventually. 

Question: Will it be fair if the father sets up no. 4 in the business, without paying back. Basically giving him a business and not giving any other brother the same.

Q: Is it sinful to have a favourite child? Or even two or three out of your children? 

Is this fair towards the others because how must they feel inside with a parent having a favourite?

Q: If a father gifts his property to one son only instead of all the legal heirs during his life, in this connection is the said gifted property is valid or not under Islamic law? 

Q: Is it fine for a father to like his son more than his daughters and tell them that they are girls and they are the ones who supposed to do house chores. They are men and they don't need to do that.

Is it right for a father to be arrogant of being a man by gender which has been gifted by Allah? Is it that men are superior to women?

Q: Please advise on the following:

A father has three children. A daughter and two sons. One son is married.

The father owns a business and both the sons work for the father, while the daughter helps out occasionally.

For the son that is married, the father gave them a house, pays for their water, lights, car payments, fuel, phone payments, etc. The father also pays for numerous holidays and gives them spending money for the holidays. The son is then given a large salary at the end of every month. The father in law is also required to pay for all the daughter in laws wants.

The other son and daughter both live with the parents still and thus the basic food and housing needs are taken care of. The unmarried children are given an allowance which they use for any extras such as clothing, car payments, holidays, hobby's, etc. This often leads to a lot of conflict in the family.

My question are as follows:

1. In a case like this, is the father being fair and just to his children?

2. Is there any difference in providing gifts, or support to the married son and unmarried son/daughter?

3. Is it compulsory for the daughter to work in the business to be given the same as the son while the parents are alive?

4. If the father spends on his wife (mother), is it compulsory for the daughter in law to receive the same?

5. Is it compulsory for the husband to provide the wife with an allowance? (not to be used for any households expenses or personal needs)

6. What obligations do the parents have towards the daughter in law with regards to financial support for needs and luxuries?

7. Is it the parents responsibility to buy and pay for the married son's house, car for the daughter in law, supporting the children on the grounds that he is working in the business and is entitled to it? (this excluding a monthly salary)

Q: Do only parents have the highest position and right to be respected and kids deserve no respect? If parents don't treat every child with equality by loving one child more and not caring for the others, is it ok in shariah?

Q: I know a man in our neighbour who is married twice. He divorced his first wife and has a daughter from her who is living with him not with her mother. And from the second wife he has a daughter too. But he does clear injustice between his daughters in many ways.

On social media he always posts pictures of his daughter from his current wife and never mentions the elder daughter. I know that girl is hurt by the deeds of her own father. And instead of asking her father, people ask that girl why your father does not post pics or mention you, why does he not care about you? She is always bullied by the people. What do you say about that man and will the poor girl be rewarded in the Aakhirah due to her sabar? 

Q: There are 4 sons, youngest son lives with parents, father is alive and decides to give youngest son 50% of the house share and 50% remaining to the other 3 sons. The youngest son has also purchased another house, but is living in the current one.

The other sons are not happy as they say that it was unfair for our dad to give more to the youngest, on the basis that he lives with him and in tradition the elder brothers should give youngest most.

The brother's refused the 50% share as they wanted full share, not half. Is there any sin on the father because he decided he wanted to choose who he likes to give?

Q: I want to know that if a child was expected to do certain things (provide,work etc) for the family by a certain age even when having other responsibilities isn't it only fair to expect all the other children, when they reach that age to be expected to do the same (especially since they have lesser responsibility than the first child did) as in Islam all the children should be treated equally, so just like they will have give driving lessons to the others as they did for the first child the same way the other children should be expected to do the same chores and work for the family the way the first child did.
