كتاب الإيمان
Read the English translation first, with the original Arabic directly underneath.
Narrated Abu Sa'id Al Khudri:
Allah's Messenger (ﷺ) said, "If a person embraces Islam sincerely, then Allah shall forgive all his past sins, and after that starts the settlement of accounts, the reward of his good deeds will be ten times to seven hundred times for each good deed and one evil deed will be recorded as it is unless Allah forgives it."
إِذَا أَسْلَمَ الْعَبْدُ فَحَسُنَ إِسْلاَمُهُ يُكَفِّرُ اللَّهُ عَنْهُ كُلَّ سَيِّئَةٍ كَانَ زَلَفَهَا، وَكَانَ بَعْدَ ذَلِكَ الْقِصَاصُ، الْحَسَنَةُ بِعَشْرِ أَمْثَالِهَا إِلَى سَبْعِمِائَةِ ضِعْفٍ، وَالسَّيِّئَةُ بِمِثْلِهَا إِلاَّ أَنْ يَتَجَاوَزَ اللَّهُ عَنْهَا
