From the benefits of the story of Aadam (alayhis salaam) Part 2– Imaam As-Sa’dee
بسم الله الرحمن الرحيم
And from the benefits;
It is obligatory for the slave if he falls into sin, that he hastens to repentance and confession and he says that which the two parents (Aadam and Hawaa) said, with a sincere heart and turning repentantly (to Allah); for Allah did not narrate to us the description of their repentance except that we emulate them; so that we are successful with happiness and saved from destruction.
