This hadith has been narrated on the authority of Ibn 'Uyaina through another chain of transmitters (who added the words)" the Disperser of clouds" in his narration.

وَحَدَّثَنَاهُ إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَابْنُ أَبِي عُمَرَ، جَمِيعًا عَنِ ابْنِ عُيَيْنَةَ، عَنْ إِسْمَاعِيلَ، بِهَذَا الإِسْنَادِ وَزَادَ ابْنُ أَبِي عُمَرَ فِي رِوَايَتِهِ ‏ "‏ مُجْرِيَ السَّحَابِ ‏"‏ ‏.‏
