مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ الْحُسَيْنِ بْنِ سَعِيدٍ عَنِ ابْنِ الْعَزْرَمِيِّ رَفَعَهُ قَالَ قَالَ أَمِيرُ الْمُؤْمِنِينَ (عليه السلام) وَ سُئِلَ عَنِ السَّحَابِ أَيْنَ يَكُونُ قَالَ يَكُونُ عَلَى شَجَرٍ عَلَى كَثِيبٍ عَلَى شَاطِئِ الْبَحْرِ يَأْوِي إِلَيْهِ فَإِذَا أَرَادَ اللَّهُ عَزَّ وَ جَلَّ أَنْ يُرْسِلَهُ أَرْسَلَ رِيحاً فَأَثَارَتْهُ وَ وَكَّلَ بِهِ مَلَائِكَةً يَضْرِبُوهُ بِالْمَخَارِيقِ وَ هُوَ الْبَرْقُ فَيَرْتَفِعُ ثُمَّ قَرَأَ هَذِهِ الْآيَةَ اللَّهُ الَّذِي أَرْسَلَ الرِّياحَ فَتُثِيرُ سَحاباً فَسُقْناهُ إِلى بَلَدٍ مَيِّتٍ الْآيَةَ وَ الْمَلَكُ اسْمُهُ الرَّعْدُ.
268. Muhammad Bin Yahya, from Ahmad Bin Muhammad Bin Isa, from Al-Husayn Bin Saeed, from Ibn Al-Azramy with an unbroken chain has said the following: Amir-ul-Momineen  replied when he  was asked, ‘Where do the clouds come from?’ He  as said: ‘They are on the dense trees, on the dunes, and on the shores which are a resort for them. So if Allah (azwj) Mighty and Majestic Intends to Send a wind which stirs them, and Allocates Angels to these who strike it by ‘Al-makhareeq’, and it is the lightning. So they rise up’. Then he  recited this verse: “[35:9] And Allah is He Who sends the winds so they raise a cloud, then We drive it on to a dead country, and therewith We give life to the earth after its death”, the Verse. And the Angel, its name is ‘Al-Ra’ad’ (The Thunder)’.
