Is it permissible for a husband to prevent his wife from conceiving, under the pretext that he has children from previous marriages and claims lack of money, while refusing to respond to her desire for procreation and intentionally practicing coitus interruptus during intercourse? And is the wife obligated to support her husband in his studies and give up her right to his time and her desire for conception and children?

A husband does not have the right to prevent his wife from conceiving or to practice coitus interruptus without her permission. It is disliked for a man to withdraw from intercourse with his wife before she has satisfied her desire, and some scholars have even deemed it forbidden. A husband must balance his duties and give everyone their due, including his family, and treat his wife well by dedicating a portion of his time to her.
