The Fuji artist should check Quran 4:3 if he has not found where the holly book talked abour marriage of more than one wife.
"Marry those that plases you of women, two, or three or four. But if you fear that you will not be just, then marry only one ...."
to be Just did not any way means love, there is no way any one can love others equally even your children but if you are capable and you can afford all it take to accommodate them. it is not a must.
