Offering Nafl Salah Before Duhr In Pairs Of 2 Instead Of Four Rakah
Sure you can, there is no prohibition. It is an optional prayer. Prophet (SWS) is also reported to have offered only 2 rakah nafl before Duhr Salah. There are narrations on both 4 rakah before Duhr and 2 rakah before Duhr. You can also offer 2 pairs of 2 rakah nakl Salah separately.
