3653 - وَ كَتَبَ مُحَمَّدُ بْنُ اَلْحَسَنِ اَلصَّفَّارُ رَضِيَ اَللَّهُ عَنْهُ إِلَى أَبِي مُحَمَّدٍ اَلْحَسَنِ بْنِ عَلِيٍّ عَلَيْهِ اَلسَّلاَمُ يَقُولُ : رَجُلٌ يُبَذْرِقُ اَلْقَوَافِلَ مِنْ غَيْرِ أَمْرِ اَلسُّلْطَانِ فِي مَوْضِعٍ مُخِيفٍ وَ يُشَارِطُونَهُ عَلَى شَيْءٍ مُسَمًّى أَ لَهُ أَنْ يَأْخُذَهُ مِنْهُمْ أَمْ لاَ فَوَقَّعَ عَلَيْهِ اَلسَّلاَمُ "إِذَا آجَرَ نَفْسَهُ بِشَيْءٍ مَعْرُوفٍ أَخَذَ حَقَّهُ إِنْ شَاءَ اَللَّهُ".
Hadith.3653 - Muhammad bin Al-Hasan Al-Saffar, may Allah (swt) be pleased with him, wrote to Imam Abu Muhammad Al-Hasan bin Ali (as) asking: "A man escorts caravans without the order of the ruler in a fearful place, and they agree with him on a specific payment. Is it permissible for him to take it from them or not?" Imam (as) said: "If he hires himself out for a well-known payment, he may take his due, Allah (swt) willing."
