In contrast, a minority of Muslim proponents of surrogacy argue that Islamic law recognizes the preservation of the human species as one of its primary objectives (maqasid), and allowing married couples to pursue conceiving children is part of this primary objective. They also contend that the surrogate mother cannot be accused of zina because no sexual intercourse with a non-legal husband is required for her pregnancy. Finally, they argue that the lineage of the child can be traced to the biological parents and hence questions of lineage are easily resolvable. They support this by drawing comparisons between hiring a surrogate mother and hiring a woman to breast feed one's child which is an acceptable practice under Islamic law.
