They came with him -asws ...

فَأَعْطَاهُ الرَّايَةَ فَقَالَ عَلِيٌّ يَا رَسُولَ اللَّهِ أُقَاتِلُهُمْ حَتَّى يَكُونُوا مِثْلَنَا قَالَ‏ انْفِذْ عَلَى رِسْلِكَ حَتَّى تَنْزِلَ بِسَاحَتِهِمْ ثُمَّ ادْعُهُمْ إِلَى الْإِسْلَامِ وَ أَخْبِرْهُمْ بِمَا يَجِبُ عَلَيْهِمْ مِنْ حَقِّ اللَّه فَوَ اللَّهِ لَأَنْ يَهْدِيَ اللَّهُ بِكَ رَجُلًا وَاحِداً خَيْرٌ مِنْ أَنْ يَكُونَ لَكَ حُمْرُ النَّعَمِ‏. He -saww gave it (the Flag) to him -asws . Ali -asws said: ‘O Rasool-Allah -saww ! I -asws shall fight them until they become like us’.

He -saww said: ‘Implement upon your -asws message until you descend in their courtyards, then call them to Al-Islam and inform them with what is beloved to them from the Rights of Allah -azwj , for by Allah -azwj if Allah -azwj were to Guide even one man through you -asws , it is better than if there happens to be for you than all the bounties’’. قَالَ سَلَمَةُ فَبَرَزَ مَرْحَبٌ وَ هُوَ يَقُولُ قَدْ عَلِمَتْ خَيْبَرُ أَنِّي مَرْحَبٌ الْأَبْيَاتِ.

فَبَرَزَ لَهُ عَلِيٌّ ع وَ هُوَ يَقُولُ‏ أَنَا الَّذِي سَمَّتْنِي أُمِّي حَيْدَرَةَ كَلَيْثِ غَابَاتٍ كَرِيهِ الْمَنْظَرَةِ أُوفِيهِمُ بِالصَّاعِ كَيْلَ السَّنْدَرَةِ. Salama said, ‘Marhab came for duel and he was saying, ‘ Khyber has known that I am Marhab ’ – the couplets. So, Ali -asws duelled to him and he -asws said (a poem): ‘ I -asws am the one my -asws mother -asws named me -asws as ‘Haider’, like a lion of the forest, destruction is (in) the scene.

I -asws shall fulfil them the measure of all the attrition ’. فَضَرَبَ مَرْحَباً فَفَلَقَ رَأْسَهُ فَقَتَلَهُ وَ كَانَ الْفَتْحُ عَلَى يَدِهِ- أَوْرَدَهُ مُسْلِمٌ فِي الصَّحِيحِ‏. He -asws struck Marhab and split his head and killed him, and the victory was upon his -asws hands – As reported by Muslim in his ‘Saheeh’’.

وَ رَوَى أَبُو عَبْدِ اللَّهِ الْحَافِظُ بِإِسْنَادِهِ عَنْ أَبِي رَافِعٍ مَوْلَى رَسُولِ اللَّهِ ص‏ قَالَ خَرَجْنَا مَعَ عَلِيٍّ ع حِينَ بَعَثَهُ رَسُولُ اللَّهِ ص فَلَمَّا دَنَا مِنَ الْحِصْنِ خَرَجَ إِلَيْهِ أَهْلُهُ فَقَاتَلَهُمْ فَضَرَبَهُ رَجُلٌ مِنَ الْيَهُودِ فَطَرَحَ تُرْسَهُ مِنْ يَدِهِ فَتَنَاوَلَ عَلِيٌّ ع بَابَ الْحِصْنِ فَتَتَرَّسَ بِهِ عَنْ نَفْسِهِ فَلَمْ يَزَلْ فِي يَدِهِ وَ هُوَ يُقَاتِلُ حَتَّى فَتَحَ اللَّهُ عَلَيْهِ And it is reported by Abu Abdullah the memoriser by his chain, from Abu Rafie a slave of Rasool-Allah -saww .
