One of the main duties upon man or woman is to show kindness towards his/her parents because Allah Almighty says: “Thy Lord has decreed, that you worship none save Him, and (that you show) kindness to parents. If one of them or both of them attain old age with thee, say not ‘Fie’ unto them nor repulse them, but speak unto them a gracious word.” (Al-Isra’: 23)
Parents’ expenses are children’s obligation if they need financial help. That is why a man came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! This son of mine was poor while I was rich, he was weak when I was strong, and I used to spend on him from my money. Then when I became poor, he, however, refused me his money. Hearing this the Messenger of Allah (peace and blessings be upon him) called that son and said: “O youth, there is no stone nor land but weeps for the affair of your father. Son! Spend on your father for you and your wealth belong to your father.”
A father may take from his daughter’s money if he is in need of such money. He should not take from the wealth of his children simply for the sake of accumulating wealth.
In his regard Shaikh M. S. Al-Munajjid, a prominent Saudi Muslim lecturer and author, states the following: “This hadith includes both sons and daughters. This is also indicated by the hadith of `A’isha (may Allah be pleased with her) in which the Prophet (peace and blessings be upon him) said: “The best of that which you consume is that which you earn, and your children are part of that which you earn.” (Narrated by the five.)
However, this is subject to the condition that it does not cause any harm to the child, whether male or female, because the Prophet (peace and blessings be upon him) said: “There should be neither harming nor reciprocating harm.” And there is further evidence, which supports this point. The father should not take from the wealth of his children simply for the sake of accumulating wealth, rather he should just take that which he needs.”
