Some students of knowledge criticize the imam in tarawih for praying more than thirteen rak'ahs. What is the guidance?

Question:
Honorable Shaykh, may Allah grant you success. This questioner says: We spent Ramadan in the Prophet’s city, and some students of knowledge prevented the brothers from praying more than thirteen rak'ahs, meaning tarawih and qiyam on the same night. They also prevented them from performing the du'a of qunut, because they say it contains something of bid'ah (religious innovation). He asks: Is their criticism correct?

Answer:
O brothers, if a person sees something, he does it for himself and does not criticize people for what they are doing. They do what they see as sunnah (recommended practice), and you do what you see as sunnah. Do not criticize people; perhaps they are more correct than you and better than you. There is no doubt that unity and bringing words together is obligatory. As for the disagreement, where they leave the imam and say he is an innovator because he prays more than thirteen rak'ahs, and that the increase is bid'ah—who said this? Who said that the increase is bid'ah? If so, the Rightly Guided Caliphs, the Muhajireen, and the Ansar would be innovators, because they prayed it in the mosque of the Messenger of Allah (peace and blessings be upon him). In the time of 'Umar, they prayed twenty-three rak'ahs. If so, they are innovators according to you. We ask Allah for safety. If a person sees something, he does not impose it on people unless he has clear evidence of its correctness and the error of the others. As for matters of ijtihad (independent legal reasoning) and matters of this kind, a person does what is stronger in his view for himself, but he does not impose it on people or criticize them for it. Yes.
