عَنْ عِمْرَانَ بْنِ حُصَيْنٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَا تَزَالُ طَائِفَةٌ مِنْ أُمَّتِي يُقَاتِلُونَ عَلَى الْحَقِّ ظَاهِرِينَ عَلَى مَنْ نَاوَأَهُمْ حَتَّى يُقَاتِلَ آخِرُهُمُ الْمَسِيحَ الدَّجَّالَ» . رَوَاهُ أَبُو دَاوُد
Translation
‘Uqba b. Malik reported the Prophet as saying, “When I send out a man and he does not fulfil my command, are you unable to appoint in his place one who will fulfil my command?" Abu Dawud transmitted it.
