‘Abdallah b. Mas'ud reported God’s messenger as saying, “He who repents of a sin is like him who has committed no sin.” In Majah and Baihaqi, in Shu'ab al-iman, transmitted it, the latter saying its only transmitter was an-Nahrani who is unknown. In Sharh as-sunna a tradition traced no farther back than him is transmitted in which he said, “Nadam is repentance, and he who repents is like him who has committed no sin.”
وَعَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «التَّائِبَ مِنَ الذَّنْبِ كَمَنْ لَا ذَنْبَ لَهُ» . رَوَاهُ ابْنُ مَاجَهْ وَالْبَيْهَقِيُّ فِي شُعَبِ الْإِيمَانِ وَقَالَ تَفَرَّدَ بِهِ النَّهْرَانَيُّ وَهُوَ مَجْهُولٌ. وَفِي (شَرْحِ السُّنَّةِ) رَوَى عَنْهُ مَوْقُوفًا قَالَ: النَّدَمُ تَوْبَةٌ والتَّائبُ كمن لَا ذَنْبَ لَهُ
