Hadith 4:9
8875. Ibn Fudayl narrated to us, from Yahya, from Abu Salamah, from Abu Hurayrah, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Whoever fasts Ramadan out of faith and seeking reward, his past sins will be forgiven."
حدثنا بن فضيل عن يحيى عن أبي سلمة عن أبي هريرة قال قال رسول الله صلى الله عليه وسلم من صام رمضان ايمانا واحتسابا غفر له ما تقدم من ذنبه
