Holy Quran:
“It is forbidden to marry your mothers, daughters and sisters…”
(Al-Nesa, v.23)
it is obvious that family marriage causes many connate and retard eternal problems. The closer this family relationship, the more capable of affecting by these sort of diseases. Is forbidding this kind of marriage in vain?!
