May Allah be pleased with you, is certain to be answered. When Allah is pleased with someone, He helps him or her overcome their difficulties, eases their hardships and guides them to success in life. The duty required of children with respect to financial support of their parents is to provide them with what is reasonable according to their means. A son of moderate means cannot be expected to provide his parents with the same standard of living as a much wealthier son. Although we speak of this as kind treatment by children, it is indeed a repayment of a debt.
Parents look after their children when they are young and helpless.
A child takes what he or she is given unaware of how much effort his father puts in order to earn his money. When the child grows up and his parents are in need of his support, that support must come naturally, without letting the parents feel themselves to be a burden on their children. Apart from financial support, a child must respect and honour his parents and extend to them the sort of treatment which befits their position as parents. In any social occasion, and even when they go out together on the street, a son must not precede his father or take a higher or more favourable position than his. He should always allow him to take precedence.
