Praise be to Allaah.
It is not obligatory for the man to have intercourse with his
wife on the wedding night. They may delay that until the time that they
choose. But intercourse -- in general -- is obligatory, and it is the right
of both spouses, and the wife must allow the husband to do that when he
wants, so long as it is not harmful to her, and the husband must have
intercourse with his wife as much as suffices her, so long as it does not
weaken him physically or distract him from earning a living.
