أَخْبَرَنِي أَحْمَدُ بْنُ الْمُعَلَّى بْنِ يَزِيدَ، قَالَ: حَدَّثَنَا صَفْوَانُ بْنُ صَالِحٍ، قَالَ: حَدَّثَنَا الْوَلِيدُ، قَالَ: حَدَّثَنَا مَالِكٌ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: إِذَا أَسْلَمَ الْعَبْدُ فَحَسُنَ إِسْلَامُهُ كَتَبَ اللَّهُ لَهُ كُلَّ حَسَنَةٍ كَانَ أَزْلَفَهَا، وَمُحِيَتْ عَنْهُ كُلُّ سَيِّئَةٍ كَانَ أَزْلَفَهَا، ثُمَّ كَانَ بَعْدَ ذَلِكَ الْقِصَاصُ؛ الْحَسَنَةُ بِعَشَرَةِ أَمْثَالِهَا إِلَى سَبْعِمِائَةِ ضِعْفٍ، وَالسَّيِّئَةُ بِمِثْلِهَا إِلَّا أَنْ يَتَجَاوَزَ اللَّهُ عَزَّ وَجَلَّ عَنْهَا

Book [47]: The book of faith and its signs
Chapter [16]: Mentioning the branches of faith

Ḥadīth [4998]: It was narrated that Abī Sa’īd al-Khudrī (may Allāh be pleased with him) said: The Messenger of Allāh (peace and blessings of Allāh be upon him) said: “If a person accepts Islām, such that his Islām is good, Allāh will decree reward for every good deed that he did before, and every bad deed that he did before will be erased. Then after that will come the reckoning; each good deed will re rewarded ten times up to seven hundred times. And each bad deed will be recorded as it is, unless Allāh, the Mighty and Sublime, forgives it.”

“When someone becomes a good Muslim” means his heart also harmonizes with his tongue, and his Islām passes beyond his tongue and descends into his heart and reaches all his bodily organs and limbs. He neither remains a hypocrite nor a transgressor.
