Burton suggests that the idea that naskh can be explained as "takhfīf" (lightening) is of limited usefulness because it is applied to both naskh that make things easier for Muslims in the temporal world — like no longer requiring lengthy nocturnal prayers or lowering the number of enemies each Muslim warrior is expected to vanquish; and abrogation that makes things more difficult — for example, the extension of the ritual fast from a few days () to the entire month of Ramadan (). Here the changes are claimed to be lightening because they will help Muslims attain a greater reward in the Hereafter. Still other abrogation — such as the switching of the "qibla" — would seem to have no effect on the difficulty or ease for Muslims of either temporal life or the afterlife.
