A relative of mine has been diagnosed with a rare and terminal form of cancer. The doctors have said that this form of cancer is incurable and has a limited life expectancy, usually between 3 months to 9 months, in certain cases 2 years maximum. He is undergoing intensive chemotherapy and has applied for a certain trial drug from America, which doctors say was developed for this specific type of cancer. His condition is not improving and it seems that doctors are uncertain about the outcome of the trial drug which has not been used on humans yet, hence the results of use are even more uncertain. He is not in a good frame of mind currently as the hope seems slim. Please comment in the light of the Shariah.
