What is the legal basis for the existence of lineage for children born through modern in vitro fertilization techniques?
If fertilization occurs using the man’s semen, and then it is implanted in the womb of the legitimate family and the child is born, then the owner of the sperm is considered the father according to Islamic law and custom, because the child is the fruit of his semen, and the wife who gave birth to the child is the legitimate mother, as He said: (Their mothers are none but those who gave birth to them) [Surat Al-Majdal: 2].
