To what extent is filial piety due, and which takes precedence: preparing the apartment or Hajj, and helping the husband's brother, which will cost a large sum, especially since the wife fears losing her rights and the rights of her children?

Filial piety is one of the greatest acts of obedience, and a wife should assist her husband in showing dutifulness to his mother and enduring any harm from her. The husband should ward off his mother's harm from his wife without being undutiful to her. The husband is not obliged to comply with his mother's request for money if she is not in need of it or if it causes him hardship, but he should treat her kindly and give her what pleases her. The husband is not obliged to buy a necklace for his brother, but he may do so as a way of maintaining kinship ties or as a loan. If the Hajj is voluntary or the Hajj of Islam and he acquires the money after the season, then buying the necklace takes precedence. However, if he acquires the money before the season, then the Hajj of Islam takes precedence. Planning for the children's future and saving money for them is good, but it should not be an unsettling obsession, for Allah Almighty has guaranteed the provision for His creation.
