Adam repents and supplicates to Allah

It was reported that the above Ayah is explained by Allah's statement,

قَالاَ رَبَّنَا ظَلَمْنَآ أَنفُسَنَا وَإِن لَّمْ تَغْفِرْ لَنَا وَتَرْحَمْنَا لَنَكُونَنَّ مِنَ الْخَـسِرِينَ

A question arises here as to how Satan got into Paradise for seducing Adam and Hawwa (علیہما السلام) when he had already been expelled from there for refusing to prostrate himself. There are many possible ways in which he can have played his trick. Possibly he never met them, but planted the suggestion in their minds from afar - a thing which Satan can always do, and of which we have a specimen in the work of the hypnotists. It is equally possible that Satan, being one of the jinns whom Allah has given certain unusual powers denied to man, assumed the shape of a snake or of something else, and thus succeeded in entering Paradise. Perhaps it was because of this disguise that Adam (علیہ السلام) did not remember Allah's warning that Satan was his enemy. According to the Holy Qur'an, Satan assured them on oath that he was one of their well-wishers (7:21). It apparently suggests that he did actually meet them, and speak to them face o face.

The Holy Qur'an says that Satan فَأَخْرَ‌جَهُمَا :"brought them out" of the state in which they had been living. In actual fact, they were 'brought out' under a divine command, but since Satan served as a means and as an intermediary, the action has been attributed to him.17
