Is it permissible to delay pregnancy for the duration of breastfeeding?

Question:
This is the answer to the following question. He says: We practiced coitus interruptus during the time of the Messenger of Allah (peace and blessings be upon him) while the Qur'an was being revealed until its end. Is it permissible to breastfeed and raise the child for two years in order to care for him and devote oneself to his upbringing?

Answer:
This is the default ruling. The default is that a woman breastfeeds her child for two years, because Allah the Exalted said: The two complete years are the duration of breastfeeding if the husband and wife agree to it. If they agree to wean him from them and give him dry milk, by their choice and consultation, there is no harm, provided it does not harm him and he accepts this. Otherwise, the better and more preferable option is to continue, with the woman breastfeeding her child and treating him well for two complete years. If necessity and public benefit call for weaning, and they consult on this and agree to wean him after one year or after a few months, and he is breastfed by someone other than his mother, there is no blame on them.
