..::..Beautiful Du'aa from the Authentic Hadeeth..::..

اللهمَّ إنِّي أعُوذُ بِكَ مِنْ جَهْدِ الْبَلَاءِ، وَدَرَكِ الشَّقَاءِ، وَسُوءِ الْقَضَاءِ، وَشَمَاتَةِ الْأَعْدَاءِ
Allahumma Inni A'oozu bika min jahdil balaai wa darkiShaqaai wa sooilQadhai wa shamatatilA'adai

O Allah! I seek refuge in You from severe trials and hardships, to be overtaken by wretchedness and bad fate and rejoicing of enemies. Allahumma Aameen.
[Saheeh Al Bukhari #6347]
