سُبْحَانَ الَّذِي يُسَبِّحُ الرَّعْدُ بِحَمْدِهِ وَالْمَلَائِكَةُ مِنْ خِيفَتِهِ
Glory is to the One whom thunder glorifies with praise and so do the angels out of fear of Him.

اللَّهُمَّ حَوَالَيْنَا وَلَا عَلَيْنَا، اللَّهُمَّ عَلَى الْآكَامِ وَالظِّرَابِ وَبُطُونِ الْأَوْدِيَةِ وَمَنَابِتِ الشَّجَرِ
O Allah, around us and not upon us. O Allah, on the hills, mountains, valleys and places where trees grow.
