Buying and Selling: Selling a Charitable Endowment Due to Disputes Among Beneficiaries
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 2105
If a dispute arises between the beneficiaries of a charitable endowment to the extent that it is supposed that not selling the endowment may result in the loss of property or the loss of life, then selling the endowment is problematic [i.e. based on obligatory precaution, it must not be sold]. However, if the endower makes a condition that it must be sold if it is advisable, then there is no problem in selling it in this case.
