Is a person considered to be committing a sin if he visits his mother, who bore him out of wedlock, and gives her money out of fear of God's punishment, but conceals from people that she is his biological mother for fear of contempt? And is he obligated to maintain ties with his biological father, who acknowledged him judicially, knowing that a child born out of wedlock is not attributed to his father?

The acts committed by the mother—fornication and abandoning the child to be raised by others, severing ties with him—are considered grave sins. Nevertheless, her right as a mother remains, and Allah has enjoined kindness to parents and commanded companionship with them in a good manner, even if they strive to make the child associate partners with Allah. Allah Almighty says: "And We have enjoined upon man [care] for his parents. His mother carried him through hardship upon hardship, and his weaning is in two years. Be grateful to Me and to your parents; to Me is the [final] destination. But if they endeavor to make you associate with Me that of which you have no knowledge, do not obey them but accompany them in [this] world with appropriate kindness and follow the way of those who turn back to Me [in repentance]. Then to Me will be your return, and I will inform you about what you used to do." One must repent to Allah for any manner of treating the mother that goes against accompanying her with appropriate kindness.

The woman who raised you is unlawful for you to touch or be alone with, as is her daughter, unless she breastfed you or a woman whose suckling established a prohibited degree of kinship breastfed you.

The preponderant opinion, which is the view of the majority, is that a child born of adultery is not attributed to his father from adultery, even if he acknowledges him.
