4) CAN ONE PERFORM THE SALAT (RITUAL PRAYER) TWICE?
The first contradictory hadith: If a man performs the salat at home and then performs the same salat once more, the second one will be superfluous.

The second hadith contradicts both the first hadith and the Quran. A superfluous prayer could not possibly be frowned on. This approach would prevent the faithful from invoking God once more.
