Mercy of Allah

Here is a SaHeeH (Authentic) hadeeth on the mercy that  Allāh has on those servants who do tawbah naṣūḥa (sincere repentance).

مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنْ مُعَاوِيَةَ بْنِ وَهْبٍ قَالَ سَمِعْتُ أَبَا عَبْدِ اللَّهِ ع يَقُولُ إِذَا تَابَ الْعَبْدُ تَوْبَةً نَصُوحاً أَحَبَّهُ اللَّهُ فَسَتَرَ عَلَيْهِ فِي الدُّنْيَا وَ الْآخِرَةِ فَقُلْتُ وَ كَيْفَ يَسْتُرُ عَلَيْهِ قَالَ يُنْسِي مَلَكَيْهِ مَا كَتَبَا عَلَيْهِ مِنَ الذُّنُوبِ وَ يُوحِي إِلَى جَوَارِحِهِ اكْتُمِي عَلَيْهِ ذُنُوبَهُ وَ يُوحِي إِلَى بِقَاعِ الْأَرْضِ اكْتُمِي مَا كَانَ يَعْمَلُ عَلَيْكِ مِنَ الذُّنُوبِ فَيَلْقَى اللَّهَ حِينَ يَلْقَاهُ وَ لَيْسَ شَيْ‏ءٌ يَشْهَدُ عَلَيْهِ بِشَيْ‏ءٍ مِنَ الذُّنُوبِ

From Mu`āwiyah bin Wahab said, I heard Abā `Abd Allāh (عليه السلام) and he said: “When a servant does a sincere repentance, Allāh loves him, and covers (protects) him in this world and the next.” I (the narrator) said: “And how does he cover (protect) him?” He (عليه السلام) said: “He makes the angels forget what they have written against him from his sins and he inspires his limbs to hide his sins, and he will inspire the places of the earth to hide what is known from his sins. So Allāh meets him, and when he meets Him, there will be nothing from the sins to testify against him”
