Imam sheds light on the subject through his famous book "an exposition on Forty Hadith" as following:
It is better if today we reflect upon our good deeds, and rationally evaluate our worships.
We should try to judge them justly, and see whether we deserve to be rewarded and praised on their basis, or if we should be reproached, punished, and condemned because of them.
And if God Almighty were to deliver us into the flames of His wrath on account of these deeds, which are good and virtuous in our own view, is He justified or not in doing so?
Now I make you arbiter to judge with justice the following matter after deliberation and profound thinking. My question is that if the Holy Prophet (S), whose truthfulness is confirmed, were to say to you, ‘It makes no difference in afterlife whether you worship God throughout your life, obey His commands, and resist lusts and carnal desires, or if you lead a life violating His commands and following your wishes and sensual desires.
This behavior of yours will not affect your station in the Hereafter.
In both cases you will attain salvation and will be sent to Paradise and saved from His chastisement.
It will not make any difference whether you offer prayers or whether you indulge in fornication and sin.
However, the good pleasure of God Almighty lies in this that you should worship Him, praise Him and thank Him, and resist your sensual desires in this world, although you will not be rewarded for it.’ Were you offered this option, would you choose to be His worshipper or a sinner?
