Is it just for a son to incur debt to buy a sacrificial animal or give a gift to please his parents, knowing that he is accumulating debt and facing difficult financial circumstances and family priorities, while his parents are well-off?

Scholars have unanimously agreed on the obligation of a child to provide for their indigent parents. It is apparent from the question that the parents are not indigent, so their maintenance is not obligatory for their child. However, providing for them is part of perfecting kindness towards them, and it is among the best forms of spending and carries the greatest reward from Allah. We advise the son to be keen on pleasing his parents by all means possible, even if it leads to incurring debt. The wife has no right to prevent him from spending on his parents and sister; rather, she should encourage him to do so, for his kindness towards them is a source of righteousness for him in his religion and worldly life. If a man is able to combine giving to his parents with the obligatory maintenance for his wife and children, he should do so. If he is unable, then the priority in that case is the maintenance of his wife and children.
