« […] Know also that this age has been engulfed by the ocean of sins, we have been struck by its waves, and its darkness has piled up, to the extent that creatures are unable to free themselves with the exception of the realized and truthful one or he who is closed to his station or the person who is under the attraction of divine providence.
Apart from these, all others are marked by the incapacity to get out from sins. Given that this situation is decreed by our Supreme Master, Exalted is His Majesty, then the reasonable person, having corrected his obligatory deeds, should attend to the expiation of his sins. By the grace of ALLAH the Most High, there are many methods of expiation. If a person has sinned profusely and devotes himself to expiation and makes great effort to repel his sins as much as possible, this will diminish the heap of sins, and he is better than the person who throws himself into sin without accomplishing any expiation.
ALLAH The Most High said: “…Verily, the good deeds remove the evil deeds…” (Sourate 11, verse 114)
And the Messenger of ALLAH (peace and blessings be upon him): « Follow a bad deed by a good one and it will be wiped away. » or words to that effect.
This is similar to a person who regularly suffers from sores on his body and who hastens to apply the medicine as soon as a new sore appears. Of course, this is better than the person who is afflicted with sores that he does not treat and says: “treatment is useless because they are so many of them.”
