عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَبْدِ اللَّهِ بْنِ الصَّلْتِ عَنْ رَجُلٍ مِنْ أَهْلِ بَلْخَ قَالَ كُنْتُ مَعَ الرِّضَا (عليه السلام) فِي سَفَرِهِ إِلَى خُرَاسَانَ فَدَعَا يَوْماً بِمَائِدَةٍ لَهُ فَجَمَعَ عَلَيْهَا مَوَالِيَهُ مِنَ السُّودَانِ وَ غَيْرِهِمْ فَقُلْتُ جُعِلْتُ فِدَاكَ لَوْ عَزَلْتَ لِهَؤُلَاءِ مَائِدَةً فَقَالَ مَهْ إِنَّ الرَّبَّ تَبَارَكَ وَ تَعَالَى وَاحِدٌ وَ الْأُمَّ وَاحِدَةٌ وَ الْأَبَ وَاحِدٌ وَ الْجَزَاءَ بِالْأَعْمَالِ.
296. A number of our companions, from Ahmad Bin Muhammad, from Abdullah Bin Al-Salt, from a man from the people of Balkh who said: I was with Al-Ridha  in his  journey to Khurasan. One day he  called for the spread (for a meal) to be set up for him . So there gathered around him  his  black friends and others. So I said, ‘May I be sacrificed for you , if you  could isolate the spread for these people’. So he  said: ‘Muuh! (Shhhh!). The Lord (azwj) Blessed and High is One, and the mother is one, and the father is one, and the Recompense is by the deeds’.
