What is the significance of fragrance emanating from a qabar?

Answer

Although a sweet fragrance from a Qabar is not explained by the Hadith, nevertheless, it is a very good sign. Such fragrances do emanate from the Quboor of some Auliya and Shuhada. If the fragrance is due to atar or some fragrant plants on the Qabar, then surely this will be quite apparent. But fragrance being emitted from within the Qabar, is certainly a very good sign indicating the good status of the mayyit. Such fragrance from within the grave reaching the outside is most certainly not the effect of any atar on the freshly buried mayyit covered by tons of sand.
