Prayer: Can We Join During the Second-Rak‘ah Tashahhud and Then Continue the Prayer?

English:

Question #565:

There are times when we attend the congregational prayer and the imam is reciting the tashahhud of the last rak‘ah. Here to get its reward, we can say takbīrah al-iḥrām, sit, recite tashahhud with the imam and stand up when the imam finishes his salām, to start the first rak‘ah. Can we do the same thing in the tashahhud of the second rak‘ah of a four-rak‘ah prayer?

Answer #565:

The above mentioned procedure is specific to the final rak‘ah of the congregational prayer so that one may acquire the reward of the congregation.
