for his daughter by lineage, and may travel with her wherever he wishes, he is likewise an unmarriageable male relative for his foster daughter. These, then, are four rulings of lineage that are established through foster-nursing. But do the rulings established through foster-nursing equal those established through lineage? In reality, they do not equal them in every respect. A person’s attachment to his foster daughter, foster sister, or foster niece is not like his attachment to one who holds that status through lineage. He does not have the same restraining reverence for his foster daughter as he has for his daughter by lineage, nor for his foster niece as for his niece by lineage. Indeed, if she is a beautiful young woman, a sinful thought may arise in him. So do not imagine that, when the scholars, may Allah have mercy on them, said that foster-nursing shares with lineage in these rulings, they meant that it is equal to it. We may prevent a man from being alone with his foster daughter, or with his foster niece through his brother or sister, because the reverence he feels in his heart toward relatives by lineage is greater. He would not dare to kiss his daughter by lineage out of desire, but he may dare to kiss his foster daughter out of desire.
These, then, are four rulings of lineage that are established through foster-nursing; none of the other rulings are established. Financial maintenance is not established: a person is not obliged to spend on his foster daughter as he must spend on his daughter by lineage. Nor is inheritance established: his foster daughter inherits nothing from him. Likewise, the collective liability for blood money in cases of accidental killing and similar cases is not established through foster-nursing, nor is the obligation to maintain ties of kinship. Thus, of all the rulings associated with lineage, only four are established through foster-nursing: marriage, looking, seclusion, and unmarriageability.
