Mazariat In Islam (اسلام میں مزارعت)
The word is Mazaareyat
All economic transactions are Halal which do not have any immoral aspect in them primarily relating to usurping wealth of others via unfair means. Mazariat is not unethical however each contract needs to be reviewed separately for any unethical aspects in it. But Mazariat cannot be declared Haram by default and neither is its income Haram .
