It should be clear that there is no conflict between the wife’s right to have a separate house and the husband being dutiful to his parents. It is incumbent on the husband to be dutiful to his parents and take care of their needs. At the same time, the wife has the right to ask for a separate house and there is nothing wrong with moving to a separate house if the husband still takes care of his parents.

However, if their health requires someone to look after them all the time, the parents may have to move in with the son (perhaps temporarily). Or perhaps the siblings could take turns staying with the parents, or the parents could stay with another of their children.

Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states: A person’s duty towards his parents comes second only to his duty towards Allah. Allah says: [Your Lord has decreed that you worship none but Him, and that you shall render utmost kindness to your parents] (Al-Israa‘ 17:23).
This, however, does not mean that he can be neglectful or complacent of his duties towards his spouse and children. The Prophet (peace and blessings be upon him) said, “There is no sin worse than a person’s wilful neglect of his own family (that is, wife and children).” A Muslim ought to balance his duties towards his wife and children with those that he owes towards his parents and other blood relations. Since Islam is a religion of balance, one is supposed to balance both these duties.
