Dua for rain

اَللّٰهُمَّ اسْقِنَا غَيْثًا مُّغِيْثًا هَنِيْئاً مَّرِيْئًا مُّرِيْعًا غَدَقاً مُـجَلَّلاً سَحّاً عَامّاً طَبَقاً دَائِماً نَّافِعًا غَيْرَ ضَارٍّ عَاجِلاً غَيْرَ آجِلٍ

O Allah shower upon us beneficial rain, which is pleasant, which will cause growth, in great abundance that, will cover the ground, that will flow spreading far and wide, such rain that is continuous, beneficial and not harmful, that will descend immediately and not after delay.
