Narrated Abu Huraira.: Once Allah's Apostle offered two rak`at and finished his prayer. So Dhul-Yadain asked him, Has the prayer been reduced or have you forgotten? Allah's Apostle said, Has Dhul-Yadain spoken the truth? The people replied in the affirmative. Then Allah's Apostle stood up and offered the remaining two rak`at and performed Taslim, and then said Takbir and performed two prostrations like his usual prostrations, or a bit longer, and then got up.
