١ـ أَحْمَدُ بْنُ مُحَمَّدٍ الْكُوفِيُّ عَنْ عَلِيِّ بْنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ عَلِيِّ بْنِ أَسْبَاطٍ عَنْ عَمِّهِ يَعْقُوبَ بْنِ سَالِمٍ عَنْ أَبِي بَصِيرٍ قَالَ سُئِلَ أَبُو عَبْدِ الله (عَلَيهِ السَّلام) عَنِ الرَّجُلِ يَكُونُ لَهُ الْحَاجَةُ إِلَى الْمَجُوسِيِّ أَوْ إِلَى الْيَهُودِيِّ أَوْ إِلَى النَّصْرَانِيِّ أَوْ أَنْ يَكُونَ عَامِلاً أَوْ دِهْقَاناً مِنْ عُظَمَاءِ أَهْلِ أَرْضِهِ فَيَكْتُبُ إِلَيْهِ الرَّجُلُ فِي الْحَاجَةِ الْعَظِيمَةِ أَ يَبْدَأُ بِالْعِلْجِ وَيُسَلِّمُ عَلَيْهِ فِي كِتَابِهِ وَإِنَّمَا يَصْنَعُ ذَلِكَ لِكَيْ تُقْضَى حَاجَتُهُ قَالَ أَمَّا أَنْ تَبْدَأَ بِهِ فَلا وَلَكِنْ تُسَلِّمُ عَلَيْهِ فِي كِتَابِكَ فَإِنَّ رَسُولَ الله (صَلَّى اللهُ عَلَيْهِ وآلِه) قَدْ كَانَ يَكْتُبُ إِلَى كِسْرَى وَقَيْصَرَ.
1. Ahmad ibn Muhammad al-Kufi has narrated from Ali ibn al-Husayn ibn Ali ibn Asbat from his uncle, Ya’qub ibn Salim from abu Basir who has said the following: “Abu ‘Abd Allah  was asked about the case of a man who needs help from a Majusi (Zoroastrian) or a Jew, a Christian or that he is a farm employee of the influential people of his land and writes to him for an important need, should he begin by offering greetings of peace to the chief in writing, knowing that he does it for help? The Imam said, ‘Do not start with his name, however, you may offer him greetings of peace in your letter. The Messenger of Allah would write to Kisra and Qaysar.’”
