Is a divorce effected by a man's saying to his wife, "Children from me are forbidden to you," with the intention of coitus interruptus, not intercourse, while he was in a state of anger?

The ruling on a man forbidding himself from intercourse with his wife without 'azl (coitus interruptus) is not clear, and it is more cautious to offer an expiation for an oath (kaffarat yamin) if he has intercourse with her in that manner. This oath is not considered an ila' (a vow to abstain from sexual intercourse); for ila' is an oath to abandon intercourse. And whoever swears, "I will not have intercourse with you until you become pregnant," intending causation and not a time limit, is not considered a mu'li (one who has made an ila' vow). It is not permissible for a man to practice 'azl with his wife except with her permission.
