Is it an innovation to recite Surat al-Ikhlas with a loud voice between the units of the tarawih prayer?

Question : This questioner says, Honorable Shaykh: I have seen some people in the tarawih prayer that, after finishing every four rak'ahs, the majority of the worshippers begin reciting three times with a loud voice. Once, I disagreed with a person on this matter and told him that this is an innovation. Did I err in my answer? Please guide us in this matter, and may you be rewarded.

Answer : Praise be to Allah, Lord of the worlds, and I send prayers and peace upon our Prophet Muhammad, and upon his family and his Companions, and upon those who follow them with excellence until the Day of Judgment. Your statement to this imam that separating the tarawih with the recitation of or other surahs with a loud voice is an innovation is a correct statement. For it is not reported from the Salaf (may Allah have mercy on them) that they used to separate every four rak'ahs with such an interlude. It is well known that tarawih in the time of the Prophet (peace and blessings be upon him) was not in the form it is in now. The Prophet (peace and blessings be upon him) prayed with his Companions in the nights of Ramadan; he prayed with them for three nights and then left it off, saying, "I feared that it would become obligatory upon you." Then it was established in the time of 'Umar ibn al-Khattab (may Allah be pleased with him), meaning the gathering for it was resumed, meaning for tarawih. It is not reported from anyone that they used to separate every four rak'ahs with an interlude from the Qur'an or other than the Qur'an.
