Muzaara'ah partnership
Q: Zaid and John entered into a muzaara'ah partnership. Zaid will provide the land and seeds and John will do the planting, etc.
They have agreed that they both will have 50% ownership in the crop. They also agreed that John will then handle the sale of the crop, and they will then divide what is earned between them 50% each.
Is this partnership valid? Can John be made a wakeel to purchase seedlings as well? If the above partnership was incorrect, how should it be redone, as there are already seeds planted.
Please advise.
