Is it permissible to pray behind an innovator of an imam who does not straighten the rows, declares his intention aloud, does not pause for the opening supplication (du’a al-istiftah), recites quickly, hurries in rising from bowing and immediately prostrates, and performs collective dhikr after the prayer?

Innovations in religion are reprehensible, and the Prophet, peace and blessings be upon him, warned against them, saying: "Every innovation is misguidance."

Straightening the rows is part of the perfection of prayer, and some scholars have deemed it obligatory.

Uttering the intention verbally is not from the guidance of the Prophet, peace and blessings be upon him, and is disliked because the intention's place is the heart.

The opening supplication (Du'a al-Istiftah) is authentically reported from the Prophet, peace and blessings be upon him, and is recommended by the majority of scholars.

Rushing in recitation in a way that distorts the elongations (mudud), or the points of articulation (makharij), or the characteristics (sifat) of letters, is impermissible and invalidates the prayer if it occurs in Al-Fatihah. As for speed that does not violate tajwid, it is permissible, though slow, melodious recitation (tartil) is better.

Rushing in a way that violates tranquility (ṭuma'nīnah) in prayer is impermissible, for without tranquility, the prayer is invalidated.

Collective remembrance (adhkar) is an innovation, and a Muslim should restrict himself to the adhkar reported in the Sunnah (definition).

The Imam should be advised gently and wisely, and the Sunnah of the Prophet, peace and blessings be upon him, should be clarified with evidence.
