All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.
Subleasing is permissible, but it appears from the agreement which you mentioned that it includes a loan that results in a benefit (to the lender) and this is not permissible. Ibn Qudaamah said: “It is reported from Ubayy Ibn Ka’b, Ibn ‘Abbaas and Ibn Mas’ood that they forbade a loan which results in a benefit. He said: “…If he (the lender) conditions him (the borrower) to rent out his house to him for less than its normal rent or on the condition that he rents the house of the lender for more than its normal rent or on the condition that he gives him a gift or does any job for him, then this is even more forbidden.”
For more benefit, please refer to Fatwa 131411.
Allaah Knows best.
