اللّهُمَّ حَوالَيْنا وَلا عَلَيْـنا،
اللّهُمَّ عَلى الآكـامِ وَالظِّـراب، 
وَبُطـونِ الأوْدِية، وَمَنـابِتِ الشَّجـر
Allāhumma ḥawālaynā wa lā `alaynā. 
Allāhumma `ala ‘l-ākāmi waẓ-ẓirāb, 
wa buṭūni ‘l-awdiyati, wa manābitish-shajar.


O Allah, let the rain fall around us and not upon us, 
O Allah, (let it fall) on the pastures, hills, valleys, and the roots of trees.
