If a Masnoon Nafl Salaat, e.g. Ishraaq, is missed, could it be performed after Zuhr?

Answer

While there is no qadha for Nafl Salaat, any Nafl Salaat which one has missed, may be performed at any time later. However, the thawaab will not be the same. For example, if Ishraaq is missed, one may perform four raka'ts Nafl at any time later. But it will not be the Masnoon Ishraaq. It will be pure Nafl.
