 ١٠ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ صَفْوَانَ بْنِ يَحْيَى قَالَ قُلْتُ لِلرِّضَا (عَلَيْهِ السَّلام) قَدْ كُنَّا نَسْأَلُكَ قَبْلَ أَنْ يَهَبَ الله لَكَ أَبَا جَعْفَرٍ (عَلَيْهِ السَّلام) فَكُنْتَ تَقُولُ يَهَبُ الله لِي غُلاماً فَقَدْ وَهَبَهُ الله لَكَ فَأَقَرَّ عُيُونَنَا فَلا أَرَانَا الله يَوْمَكَ فَإِنْ كَانَ كَوْنٌ فَإِلَى مَنْ فَأَشَارَ بِيَدِهِ إِلَى ابي جعفر (عَلَيْهِ السَّلام) وَهُوَ قَائِمٌ بَيْنَ يَدَيْهِ فَقُلْتُ جُعِلْتُ فِدَاكَ هَذَا ابْنُ ثَلاثِ سِنِينَ فَقَالَ وَمَا يَضُرُّهُ مِنْ ذَلِكَ فَقَدْ قَامَ عِيسَى (عَلَيْهِ السَّلام) بِالْحُجَّةِ وَهُوَ ابْنُ ثَلاثِ سِنِينَ.
 10. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Safwan ibn Yahya who has said the following. “Once I said to al-Rida , before Allah’s granting you the blessing of the birth of abu Ja’far  we would ask you and you would say, “Allah will grant me a son and He has granted you one. His birth is the delight of our eyes. May Allah spare us from showing your (sad) day. However, if something will happen to who then (will leadership with Divine Authority) will go?” The Imam  pointed out with his hand towards abu Ja’far  and he was standing before him. I then asked, “ May Allah take my soul in service for your cause, a child of three years?” The Imam  said, “That will be of no harm to him. Jesus rose with Divine authority when he was a three years old child.”
