Leasing a rented building

A: Whoever rents a building may sublet it to someone else for the same price as that for which he rented it, or more or less than that, and for the same time period as that agreed upon or less, not for more as that may cause harm, because he has the right to make use of the thing that he has rented. Therefore it is permissible for him to make use of it himself or let someone else make use of it, unless the owner has made a condition that the renter may not transfer it to someone else, or he may not rent it to those who practice certain professions or occupations. In this case both parties are bound by the conditions that they have agreed upon. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
