Agreement between husband and wife on prevention from pregnancy

Question: Is it permissible for the husband and wife to both agree on not wanting to have a baby after Allah has already gifted them with several sons or daughters?

Answer: It’s allowed but one must see which way he chooses to take and it must be allowed, such as allowing the sperm to exit outside the woman, pulling out before the sperm exits from the man. However the operation in which the woman ties her tubes and prevents her from ever getting pregnant is a problem.
