In some fatwas, it is mentioned that the child of adultery is not attributed to his father, which is the opinion of the majority. In other fatwas, it mentions the possibility of attributing him to the father. So, what is the correct ruling on this issue, and what is the evidence for the permissibility of attribution?

Islamic law has given importance to lineage, which is a legitimate bond between a father and his son, passed on from predecessors to successors. Scholars agree that marriage (paternity) is the basis for establishing lineage. There is a disagreement among scholars regarding the attribution of a child born out of wedlock to the father, if the father claims him, with two opinions: prohibition, which is the view of the majority of scholars, and permissibility, which is the view of some scholars like Ibn Taymiyyah and Ibn al-Qayyim. The argument for permissibility has benefits including the preservation of lineages, the care for children, protecting them from homelessness and loss, achieving justice, and mitigating the effects of crime. The issue is subject to discretion and should be considered in each case based on its circumstances. If the child is at risk of losing his faith or worldly well-being, adopting the view of claiming the child achieves a legitimate interest.
