Take the example of two people. Assume they have both been granted with sufficient opportunity here on earth to earn the pleasure of Allah, and that they had been informed about what is good and what is evil; that they fulfilled their religious duties and obligations until the time of death, and spent their lives seeming as devout Muslims; and that they succeeded in all areas, that is, had good jobs and families and became respected members of the society. If people were to be asked who was the most successful of the two, in response, you might receive answers such as,"the one who was more hardworking or tenatious or who strove most strenuously." However, if we were to consider these responses carefully, we would then recognize that these defininitions of "success" are based not according to the Qur'an, but according to worldly criteria.
