To whom should he give preference, his mother or his wife?
Question

                A man has a wife and a mother. Should he give preference to his wife over his mother in spending, other necessities and clothing, and is there any sin involved if he does that?
Praise be to Allah.There is no sin involved in that, if his mother is one of
      those whom he is obliged to support and he meets her needs. But it is
      better for him to make his mother happy and to give her preference. If he
      has to give preference to his wife, he should hide that from his mother.
      And Allaah knows best.
