ANSWER:

The reward is for all prayers, even when prayed at home. 

QUESTION: Is there any benefit in remaining in the spot i offered salat? For example I offer the asr salat at home (because the masjid is too far away) and remain after the salat sitting, doing dhikr and reading quran. I know there is reward in case of offering the fajr salat in the masjid and remaining in ones spot but is there any reward for other prayers?
