عَنْ أَبِي مُوسَى رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَنَاءُ أُمَّتِي بِالطَّعْنِ وَالطَّاعُونِ فَقِيلَ يَا رَسُولَ اللَّهِ هَذَا الطَّعْنُ قَدْ عَرَفْنَاهُ فَمَا الطَّاعُونُ قَالَ وَخْزُ أَعْدَائِكُمْ مِنَ الْجِنِّ وَفِي كُلٍّ شُهَدَاءُ
Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: The destruction of my Ummah will be through stabbing and plague. Someone asked: O Messenger of Allah! We know what stabbing is, but what is plague? He (peace and blessings be upon him) replied: It is the stabbing of your enemies from among the jinn. And (whether it is plague or stabbing) there are martyrs in each.
