BASTARD زلد الزماwaladu ‘z-mina)
An illegitimate child has, according to Muslim law, no legal father, and consequently the law does not allow the father to interfere with his illegitimate child, even for the purposes of education. He cannot inherit the property of his father, but he is acknowledged as the rightful heir of his mother. (Bai1lie’s Digest, p. 432). The evidence of a bastard is valid, because he is innocent with respect to the immorality of his parents; but the Imam Malik maintains that his testimony is not to be accepted with respect to a charge of whoredom. (Hidayah, vol. ii. 692.)
