What is the Islamic view on married couples who choose to be childfree?

Summary

This Bayan Linnas explains that preserving lineage and increasing offspring are among the fundamental objectives of marriage in Islam, and that the desire for children is part of human nature, as reflected in the encouragement to marry women who are fertile and affectionate. It distinguishes being childfree, a deliberate choice not to have children, from being childless, where a couple is not granted children for biological or similar reasons. Couples without children due to infertility or illness are not regarded as deficient, and they may seek medical treatment provided it stays within the limits of the Shariah. Family planning is described as a matter involving the mutual agreement of husband and wife.
