The lineage of al-li`an child and his inheritance from his father, who denied him and performed oath of condemnation (al-mula’anah) is considered one of the crucial issues in the Sharia and the law. This is because of the serious effects of denying his lineage from his father, which leads to depriving the child of the inheritance of the father and his family. Some courts accepted the analysis of the DNA when denying the child's lineage. Based on this fact, the issue has raised, especially when there is a conflict between the father’s denial of his son and the court’s finding based on DNA result. Which one is to be accepted if the father denied while the court confirmed his child’s lineage? This study aimed at introducing al-li`an child from Sharia and legal points of view, and the importance of analyzing the genetic footprint (DNA) as a guide to be used when there is a conflict between husband and wife in their opinions. The research methods used in this study are the inductive approach by tracking the views and evidence of the Islamic jurists and examining the reasons for the disagreement among them. In comparison, the analytical and comparative methods are used to discuss and analyze the opinions of the jurists and their evidence and compare these provisions with what is being practiced in Malaysian law. This study has reached some important results among others: the child of al-li`an remains a legitimate child as long as the father did not deny his lineage. The final decision on denying or confirming child’s lineage is based on the analysis of the genetic fingerprint (DNA result). Therefore, the lineage of al-li’an child and his inheritance right remains valid or undeniable unless the analysis result of the genetic fingerprint conforms with the statement of the father who denied his child lineage through al-li`an (oath of condemnation).

Islam has approved the system of inheritance based on accepted scholars justification. In kinship, this legislation has strengthened the bonds between the heir and the bequeathed. Likewise, the inheritance between spouses as long as the marriage exists between them. And he gave the freedman the right to inherit from his slave who had freed him. This study aimed to clarify and analyze the entitlement to inheritance in Muslim new. The problem of the research lies in the one who has the priority of the inheritance in new Muslims, if there are no other justifications for inheritance. This study relied on the inductive approach, by following the opinions of the jurists and their evidence regarding the conditions for inheritance entitlement in Islam currently; and examining the entitlement of Bayt Al-Mal as the beneficiary of the new Muslims who have no heirs. It also relied on the comparative analytical method in discussing and analyzing the opinions and evidence of jurists; comparing these provisions with what is being done in the fatwa departments today. This study concluded important results, including: The Bayt Al-Mal is a custodian of Muslims' money from loss, and not an inheritor. If the owner of this money is known, it will be returned to him, and if the owner of the money is not known, it will be distributed in the interests of the Muslims. The person who guides the new Muslim should be given precedence of inheritance in the Syariah. While, a new Muslim who does not have a legal inheritance has the right to bequeath all his money to whoever was a reason for his conversion to Islam, whether he was a person or an institution.
