And even if he expresses repentance there is no guarantee of acceptance by Allah (S.w.T.). Give attention to your own hearts! Whether there are thoughts of good or of evil in your heart, you will always have doubts about these thoughts! When Satan upbraids you to commit a sinful act, the angels guide you against it. If Satan tries to prevent you from doing a good turn, the angels encourage you to go ahead with it. At the Cross-roads Man is therefore at the cross-roads!
Either he loses himself in the valley of greed and vanity or is guided by the angels to the path of virtue and salvation. Allah (S.w.T.) has created man with the faculty of making his own decisions for his actions.
(Sura al‑´Ankabut, 29:40) The door for repentance is always open Allah (S.w.T.) has further said, ‘If We had imposed Iblīs over your progeny and has given him respite till the Day of Reckoning, we have kept the doors of repentance open for you progeny too’. If men are caught in the web of the accursed Satan, they can express repentance like their ancestor, Adam (a.s.) and seek forgiveness from Allah (S.w.T.).
