ANSWER:

If he performed these two prostrations before salam, you must follow him and offer them! 

If the mistake he made was in the rakah you joined him in and he offered the sujood after the salam, you must offer it at the end of your own prayer. 

If the mistake was in the 1st two rakah of the imam which you were not present, you don’t have to offer them after you finish your own prayer.

Sheikh,Imam performed a Sahu sujud because of a mistake in the prayer. As my prayer was incomplete,(i missed 2 rakah) do I have to perform shahu sujud again while completing my prayer?

Is the reward of a house in jannah for praying 12 Rakaah Sunnah daily for someone who does it all his life and there will be one house for him. Or is it one house for one day? It means the day we pray we get one house in Jannah and the day we don’t offer these 12 Rakaah, we don’t get the house???
