عن أبي هريرة رضي الله عنه
أن رسول الله صلى الله عليه وسلم قال: «من قام رمضان إيمانًا واحتسابًا غفر له ما تقدم من ذنبه»
The Messenger of Allah (sallallahu alayhi wa sallam) said, “He who observes optional prayer (Tarawih prayers) throughout Ramadan, out of sincerity of Faith and in the hope of earning reward will have his past sins pardoned.”.
