التَّائِبُ مِنَ الذَّنْبِ كَمَنْ لَا ذَنْبَ لَهُ
Translation: One who repents of sin is like one who has no sin.
Source: Ibn Majah.
التَّائِبُ means “the one repenting”; it is an active participle. مِنَ الذَّنْبِ means “from sin.” In كَمَنْ, the prefixed kāf means “like,” while مَنْ means “someone who.” لَا ذَنْبَ لَهُ expresses “he has no sin.”
The comparison highlights the immense value of repentance and hope of forgiveness. Turning away from the wrong, genuine remorse, and a firm intention not to return to it give repentance its practical substance.
