What is the ruling on the transitional takbeer before reaching the next pillar or during it? Is it obligatory to extend the takbeer? What is the ruling on someone who mistakenly performed the opening takbeer twice?

- Whoever began the takbir for prostration and finished it before starting the prostration, it is as if he did not utter it. However, whoever began it before starting the prostration and finished it after starting the prostration has uttered it in its proper place.

- Extending the takbir of transition is recommended so that the worshipper reaches the rukn (pillar) to which he is transitioning.

- Whoever began the takbir in its proper place and finished it quickly without violating its essence, that is sufficient for him.

- Whoever inadvertently added a takbir, the prostration of forgetfulness (sujud al-sahw) is recommended for him, and his prayer is not invalidated by omitting it.
