What is the ruling on raising one's voice in sending blessings upon the Prophet (blessings and peace of Allaah be upon him) and praying that Allaah be pleased with the Rightly Guided Caliphs between the rakâahs of Taraweeh?
Praise be to Allaah.
There is no basis for that -- as far as we know â in shareeâah. Rather it is an innovation so it should not be done. Nothing will be good for the last of this ummah except that which was good for the first of it, which is following the Qur'aan and Sunnah and the path of the early generations of the ummah (the salaf) and avoiding that which differs from that.
