Taravih Prayer is the special Prayer ordained for the month of Ramadan. It has to be performed each night during the month of Ramadan. It is in fact offered at Tahajjud time. The observance of Taravih Prayer after the ‘Isha’ Prayer was allowed during the caliphate of Hadrat ‘Umar(ra), to enable such people, who for unavoidable reasons could not perform Taravih Prayer at Tahajjud time to still offer this Prayer. However, it is preferable to offer this Prayer in pre-dawn hours. The recitation of long passages from the Holy Quran during the Taravih Prayer has been in vogue among Muslims, following the practice of the Companions of the Holy Prophet(sa).
Taravih Prayer consists of eight Rak‘at, but one can offer as many as twenty or more Rak‘at if one wants to. It seems appropriate to take a little rest each time after offering four Rak‘at.
