I am using your english version heter iska contract with a non-religious jew and he is not comfortable with the line “All other profit-making assets of mine (ours) are to be conceded liable for the above-mentioned monies” first of all whats pshat of this and second does this have to be included. Also, why does he have to receive a dollar for his efforts? thanks.
The dollar is given so that the person receiving the funds should not be “working for free” for the investor, which would be an infringement of ribbis.
The line “All other profit-making assets of mine (ours) are to be conceded liable for the above-mentioned monies” is important, because it implies that the money given is actually being invested, or, if the money is not being invested, there is some other investment that justifies the profit being given to the investor.
If you wish to delete this line, you will have to ensure that the money given is actually invested in some profit-making scheme, and not merely spent by the receiver. A clause should be inserted to the effect that the money is being invested in whatever scheme it is.
