رَوَى عَلِيُّ بْنُ رِئَابٍ عَنْ أَبِي بَصِيرٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: «كَانَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ وَ أَمِيرُ اَلْمُؤْمِنِينَ عَلَيْهِ اَلسَّلاَمُ وَ مَرْثَدُ بْنُ أَبِي مَرْثَدٍ اَلْغَنَوِيُّ يُعْقِبُونَ بَعِيراً بَيْنَهُمْ وَ هُمْ مُنْطَلِقُونَ إِلَى بَدْرٍ ».
Ali ibn Ri'ab narrated from Abu Basir, from Abu Ja'far (a.s), who said: "The Messenger of Allah (swt) (peace and blessings of Allah (swt) be upon him and his family), Amir al-Mu'minin (a.s), and Marthad ibn Abi Marthad al-Ghanawi would take turns riding a camel among them as they headed toward Badr."
