The Excellence of Optional (Tawawih) Prayer during Ramadan
1187. Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (sallallaahu 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.”
[Al-Bukhari and Muslim].
1188. Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (sallallaahu alayhi wa sallam) used to urge (the people) to perform (optional Tarawih) prayer at night during the month of Ramadan. He did not order them or make it obligatory on them. He (sallallaahu alayhi wa sallam) said, “Whosoever performs (optional Tarawih) prayers at night during the month of Ramadan, with Faith and in the hope of receiving Allah’s reward, will have his past sins forgiven.”
[Muslim].
