569 - وَقَالَ اِبْنُ أَبِي لَيْلَى لِلصَّادِقِ عَلَيْهِ اَلسَّلاَمُ: أَيُّ شَيْءٍ أَحْلَى مِمَّا خَلَقَ اَللَّهُ عَزَّ وَ جَلَّ فَقَالَ «اَلْوَلَدُ اَلشَّابُّ» فَقَالَ أَيُّ شَيْءٍ أَمَرُّ مِمَّا خَلَقَ اَللَّهُ عَزَّ وَ جَلَّ قَالَ «فَقْدُهُ» فَقَالَ أَشْهَدُ أَنَّكُمْ حُجَجُ اَللَّهِ عَلَى خَلْقِهِ.
