Do jurists and the four schools of thought agree that the place for the transitional takbeers, tasmee’ (saying “Sami‘a Allahu liman hamidah”), and tahmeed (saying “Rabbana wa lakal hamd”) is between the two rukns (pillars/parts of the prayer), and is going to a distant mosque that applies this considered an act of extremism (tanattu‘)?

The 'takbirat al-intiqal' (takbirs of transition) are Sunnah according to the majority of scholars, and obligatory according to the Hanbalis. It is recommended that they begin when one starts the transition and extend until reaching the next pillar, so that no part of the prayer is devoid of remembrance. The view that the prayer is invalidated if part of the takbir occurs before or after the transition causes hardship. The correct view is that there is no harm in this, and it is better for the takbir to be between the two pillars. It is advised to pray in the neighboring mosque while gently and kindly advising the Imam. One should not abandon praying behind an Imam who does not pronounce the takbir or tasbih in its proper place; rather, he should be taught the Sunnah in this regard.
