Hadith text
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
Abu Saeed Khudri (رضی اللہ عنہ) se riwayat hai ke Allah ke Rasool (ﷺ) ne farmaya: "Jab koi shaks sacche dil se Islam qubool karta hai, to Allah uske tamam pichhle gunah maaf kar deta hai, iske baad hisaab shuru hota hai — har nek amal ka ajr das se saat sau guna tak milta hai, aur har buraai jitni ki gayi utni hi likhi jaati hai, illa yeh ke Allah use maaf kar de."
