وَقَالَ هَارُونُ حَدَّثَنَا عَمْرُو بْنُ أَبِي قَيْسٍ عَنْ مُطَرِّفِ بْنِ طَرِيفٍ عَنْ أَبِي الْحَسَنِ عَنْ هِلاَلِ بْنِ عَمْرٍو قَالَ سَمِعْتُ عَلِيًّا - رضى الله عنه - يَقُولُ قَالَ النَّبِيُّ صلى الله عليه وسلم " يَخْرُجُ رَجُلٌ مِنْ وَرَاءِ النَّهْرِ يُقَالُ لَهُ الْحَارِثُ بْنُ حَرَّاثٍ عَلَى مُقَدِّمَتِهِ رَجُلٌ يُقَالُ لَهُ مَنْصُورٌ يُوَطِّئُ أَوْ يُمَكِّنُ لآلِ مُحَمَّدٍ كَمَا مَكَّنَتْ قُرَيْشٌ لِرَسُولِ اللَّهِ صلى الله عليه وسلم وَجَبَ عَلَى كُلِّ مُؤْمِنٍ نَصْرُهُ " . أَوْ قَالَ " إِجَابَتُهُ " .
Harun said: Amr ibn Abi Qays narrated to us, from Mutarrif ibn Tarif, from Abu al-Hasan, from Hilal ibn Amr, who said: I heard Ali, may God be pleased with him, say: The Prophet ﷺ said, “A man called al-Harith ibn Harrath will emerge from beyond the river, with a man called Mansur at the head of his force. He will prepare the way—or establish power—for the family of Muhammad, just as Quraysh prepared the way for the Messenger of Allah ﷺ. Every believer must support him”—or he said, “respond to him.”
