Praise be to Allaah.
We put this question to Shaykh Muhammad ibn Saalih al-‘Uthaymeen, may Allaah preserve him, who answered as follows:
No, that is not correct, but if Allaah has made the husband rich and the wife’s position is average or less, then it is part of chivalry or manliness that he should pay for that – but it is not obligatory. And Allaah knows best.
Sheikh Muhammed Salih Al-Munajjid
