عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنِ الْحَسَنِ بْنِ عَلِيِّ بْنِ عُثْمَانَ قَالَ حَدَّثَنِي أَبُو عَبْدِ اللَّهِ الْمَدَائِنِيُّ عَنْ أَبِي عَبْدِ اللَّهِ (عليه السلام) قَالَ إِنَّ اللَّهَ عَزَّ وَ جَلَّ خَلَقَ نَجْماً فِي الْفَلَكِ السَّابِعِ فَخَلَقَهُ مِنْ مَاءٍ بَارِدٍ وَ سَائِرَ النُّجُومِ السِّتَّةِ الْجَارِيَاتِ مِنْ مَاءٍ حَارٍّ وَ هُوَ نَجْمُ الْأَنْبِيَاءِ وَ الْأَوْصِيَاءِ وَ هُوَ نَجْمُ أَمِيرِ الْمُؤْمِنِينَ (عليه السلام) يَأْمُرُ بِالْخُرُوجِ مِنَ الدُّنْيَا وَ الزُّهْدِ فِيهَا وَ يَأْمُرُ بِافْتِرَاشِ التُّرَابِ وَ تَوَسُّدِ اللَّبِنِ وَ لِبَاسِ الْخَشِنِ وَ أَكْلِ الْجَشِبِ وَ مَا خَلَقَ اللَّهُ نَجْماً أَقْرَبَ إِلَى اللَّهِ تَعَالَى مِنْهُ.
369. A number of our companions, from Sahl Bin Ziyad, from Al-Hassan Bin Ali Bin Usman who said: Abu Abdullah Al-Mada’iny narrated from Abu Abdullah  having said that: ‘Allah (azwj) Created a star in the seventh orbit. So he (azwj) Created it from cold water and the rest of the six stars flowed from hot water, and it is the star of the Prophets , and the successors  and it is the star of Amir-ul-Momineen  commanding the exit from the world, and the ascetism in it, and commanding for the dust to be the mattress, and bricks to rest upon (for a pillow), and coarse clothing, and eating the tasteless (food), and Allah (azwj) has not Created a star more closer to Allah (azwj) the High, than it’.
