(Fatwa: 1502/1044/L=12/1435)
If the husband has not given talaq to his wife then the nikah is still intact. Their nikah did not come to an end if she ran away with her friend though her friend established a physical contact with her.
Note: It is not necessary for the husband to give talaq to such a woman. If she does true taubah then the husband may keep her. [D]
