Is it permissible for someone who is performing Tarawih (a special supererogatory night Prayer in Ramadan) to pray four (Part No. 7; Page No. 200) Rak`ahs (units of Prayer) with one Taslim (salutation of peace ending the Prayer)?
Tarawih should be performed in pairs of Rak`ahs. It is authentically reported that the Prophet (peace be upon him) said, when asked about the supererogatory Salah (Prayer) at night,
"Salah during the night should consist of pairs (of Rak`ahs), but if one of you fears morning (is near), they should pray one Rak`ah, which will make their Salah odd-numbered."
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
