The Prophet (ﷺ) led us in the (prayer) at Mina (during the Ḥajj) and it was two Rak'at. [2:189-O.B.]

We offered a four Rak'at prayer at Mina behind Uthman bin ' Affan 'Abdullah bin Mas'ud was informed about it. He said sadly, "Truly to Allâh we belong and truly to Him we shall return.

He further said, "May I be lucky enough to have two of the four Rak'at accepted (by Allâh)." [2:190-O.B]

And after waiting for a short while, Iqama used to be pronounced for the 'Isha' prayer and he would offer two Rak'at and perform Taslîm.
