عَنْ عَبْدِ اللَّهِ بْنِ حَوَالَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ مَنْ نَجَا مِنْ ثَلَاثٍ فَقَدْ نَجَا ثَلَاثَ مَرَّاتٍ مَوْتِي وَالدَّجَّالِ وَقَتْلِ خَلِيفَةٍ مُصْطَبِرٍ بِالْحَقِّ يُعْطِيهِ
It is narrated from Sayyiduna Abdullah bin Hawalah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever is saved from three things will attain salvation. The Prophet (peace and blessings be upon him) repeated this statement three times: (1) My death, (2) the Dajjal, and (3) the killing of a caliph who stands firm on the right of the caliphate given by Allah Almighty.
