The Prophet (saw) said: The people who are the most severely tested are the Prophets, then the Righteous, then the next and then the next best. A person will be tested in accordance to their level of religious commitment (Islam); if they are strong in their religious commitment, the more severe their tests will be, and if there is some weakness in their commitment, their tests will be lightened for them. A person will continue to be tested until he (or she) walks upon the earth free from sin. (Ahmad)
