Dua For Rain

اللّهُمَّ اَسْقِـنا غَيْـثاً مُغيـثاً مَريئاً مُريـعاً، نافِعـاً غَيْـرَ ضَّارٌ، عاجِـلاً غَـيْرَ آجِلٍ

O Allah, shower upon us abundant rain, beneficial not harmful, swiftly and not delayed.

Pronunciation: Allaahumma 'asqinaa ghaythan mugheethan maree'an maree'an, naafi'an ghayradhaarrin, 'aajilan ghayra 'aajilin.
