Could multiple intentions be made when performing two raka'ts Nafl Salaat, e.g.

Answer

While the multiple intentions in one Nafl Salaat are valid, it is obviously not the same as performing separately, one Salaat for each intention. The best method is to perform each Salaat separately. However, if due to preoccupations you cannot find the time to perform separately, then make multiple intentions. By adopting multiple niyyats as a norm, one will be depriving oneself from great rewards. It is simple to understand that two raka'ts Nafl with multiple intentions will not be the same as performing ten raka'ts, each two raka'ts with its own niyyat.
