" Ibn ‘Abbâs said: “Many a repentant person will come on the day of resurrection thinking that he is a repentant person but he is not really a repentant person. This is because he did not fortify the doors of repentance with remorse, the determination not to repeat that sin, the determination to redress the wrongs that he did to people if possible, and to seek to absolve himself from them if possible, if not, to engage in abundant forgiveness for himself and for them so that they may be pleased with him. "
