Question: In Ramadan We find people in some Masjids (mosques) who invoke Allaah’s peace and blessings upon the Prophet, the Rightly-Guided Caliphs, the Mothers of the Believers, and the Ten Sahaabah (Companions) given the glad tidings of entering Jannah (Paradise) loudly in congregation. They do this following each two Rak`ahs (units of Prayer) of Taraaweeh (special supererogatory night Prayer in Ramadaan) in a specific order known to them. What is the ruling on this? How many Rak`ahs are there in Taraaweeh prayer? When is it performed? Is it performed on the night of the first or the second day of Ramadaan? What is the ruling on some Imaams reciting half an Aayah, one, or two short Aayaat in Taraaweeh and Maghrib prayer especially in Ramadaan?
Answer: Dhikr (Remembrance of Allaah) and invoking Allaah’s peace and blessings upon the Prophet in congregation after Fard (obligatory) or Nafilah (supererogatory) prayer, or following each two Rak`ahs of Taraaweeh is Bid`ah (innovation in religion)… read more here.
