English Translation of Hadith
Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) 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.”
[Al-Bukhari Book 03, Chapter 32, Hadith # 226].
Lesson: as mentioned above in Surah Ar-Rum [The Romans] Ayat 38. “It is they who will be successful” May Allah forgives all our sins by his grace in coming month of Ramadan. (Ameen).
