"Every born Muslim must be reconverted to Islam sometime during his life; Islam cannot be inherited. In view of this, it was alarming when a levelheaded and realistic man like Muhammad Asad, towards the end of his long life, revealed to me serious doubts as to whether as in 1926, he would again find his way to Islam, if he were again a young man in today’s Muslim world."
