Shaykh Abu Abdir Rahmaan Yahyaa Bin Alee Al-Hajooree was asked:

Question:

What is the ruling on repeating after the Adhan if the mu’adhdhin is Sufi or Shi’ee?

Answer:

“Replying to what is authentic from the adhan is Sunnah and what is newly invented, innovated, then do not repeat it after the mu’adhdhin, like [the wording] “Come to the best of deeds”. This is due to the generality of the statement of the Prophet (ﷺ):

إِذَا سَمِعْتُمُ الْمُؤَذِّنَ فَقُولُوا مِثْلَ مَا يَقُولُ

When you hear the Mu’adhdhin, repeat what he says

[Reported by Muslim, Ahmad, Abu Dawood and others from Abdullah bin ‘Amr (may Allah be pleased with him)]”

[al-Kanzuth-Thameen (2/346-347)]
