<b>Guidance from the Hadiths:</b><br> 1) It is not lawful for a person to claim to be the son of someone other than his father. This constitutes severance of kinship ties and causes broad corruption.<br> 2) They point out the keenness of Islam to preserve lineages. This is one of the excellent aspects of the Shariah.<br> 3) It is obligatory to show dutifulness to one’s father, which includes attributing oneself to him.
