Using contraceptives

Q: A couple have a new baby, the husband is in Madrasah and is not working. Parents are seeing to the costs of the baby. With this in mind, and the fact that more children may distract the husband studies, and with spacing of children in mind, are contraceptives permissible? What types of contraceptives are permissible, is the use of a condom haram?
