10 وَ بِهَذَا الْإِسْنَادِ عَنْ عَلِيِّ بْنِ حَرْبٍ [الْحَارِثِ] عَنِ الْفَضْلِ بْنِ يَحْيَى عَنْ أَبِيهِ عَنْ أَبِي عَبْدِ اللَّهِ (ع) قَالَ زُورُوا كَرْبَلَاءَ وَ لَا تَقْطَعُوهُ فَإِنَّ خَيْرَ أَوْلَادِ الْأَنْبِيَاءِ ضُمِّنَتْهُ أَلَا وَ إِنَّ الْمَلَائِكَةَ زَارَتْ كَرْبَلَاءَ أَلْفَ عَامٍ مِنْ قَبْلِ أَنْ يَسْكُنَهُ جَدِّيَ الْحُسَيْنُ (ع) وَ مَا مِنْ لَيْلَةٍ تَمْضِي إِلَّا وَ جَبْرَائِيلُ وَ مِيكَائِيلُ يَزُورَانِهِ فَاجْتَهِدْ يَا يَحْيَى أَنْ لَا تُفْقَدَ مِنْ ذَلِكَ الْمَوْطِنِ

10. With this chain of narration from Ali ibn Harb [Al-Harith] from Al-Fadl ibn Yahya from his father from Abu 'Abdullah , he said: "Visit Karbala and do not cut it off, for among the best offspring of the prophets, it has been included. Indeed, the angels visited Karbala a thousand years before my grandfather Husayn settled in it. And there is no night that passes except that Gabriel and Michael visit it. So strive, O Yahya, not to be deprived of that place."
