What are the requirements for a contract of musaqah involving a principal object and an ancillary object?
The contract of musaqah involving a principal object and an ancillary object requires that if the value of the ancillary is one third or less of the principal object, the contract must include the subsidiary object. This means that the worker under the musaqah must serve the ancillary as if it were the principal, and it is not valid to stipulate that the proceeds belong to the owner and not the worker. Furthermore, the proportion due to the worker from the proceeds must be the same as the proportion due from the principal object. The conditions for the validity of the musaqah are determined by their applicability to the principal object, not the ancillary object.
