Is paying 30,0 EGP to the wife's father to buy a cleaning machine and operate it for him in his company, in exchange for returning 2,0 EGP within 15 months and 600 EGP within 24 months, permissible or forbidden?

If the capital of the machine is guaranteed and repaid in installments over 15 months, with a profit of 600 pounds monthly for two years, this is impermissible because it is a loan that draws benefit, which is usury (riba).
