Du'aa for protection against Natural Disaster, Plague and War.
When the Muslims Community is afflicted with some hardship then Qunoot-E-Naazilah should be recited in the Fajr Salaat.
Method: After the Rukoo of the second raka'at, while standing in the position known as Qaumah, the Qunoot should be read in a voice lower in tone than when reciting the Qiraa'at. The Muqtadees should place their hands at the side and say Aameen at the proper juncture.
Note: Women may also recite this du'aa softly.
One may recite it as often as possible as a du'aa.
Translation :
O, Allah, guide us aright along with those who have been rightly guided and grant us safety along with those that have been granted safety and support us along with those that have been supported and add Your Blessings to what You have given us and save us from the harmful effects of what You have ordained ( i.e. lest I should be wanting in cheerfully submitting to your Decrees) as You alone disposes and no one can dispose against You. Anyone who is under Your Protection cannot be lowered and anyone who is opposed by You cannot gain dignity; our Lord; You are full of blessings and Most High, we beg forgiveness from You and repent before You and may the blessings of Allah be showered on the Holy Prophet (sallallahu alayhi wasallam). O Allah, forgive us and the believing men and women and Muslim men and women, unite their hearts with mutual love, set right their mutual affairs and help them against theirs and Your enemy. O Allah, let Your curse be on those unbelievers who prevent people from treading Your path, who reject Your prophets and fight Your chosen ones. O Allah, make difficult their plans, shake their feet and give them such punishment which is not turned away from a sinning people.
Aameen
