Supplications for when in anguish

لَآ إِلٰهَ إِلَّا اللهُ الْعَظِـيْمُ الْحَلِـيْمْ، لَآ إِلٰهَ إِلَّا اللهُ رَبُّ الْعَـرْشِ الْعَظِيْمِ، لَآ إِلٰـهَ إِلَّا اللهُ رَبُّ السَّمٰوٰتِ وَرَبُّ الْأَرْضِ وَرَبُّ الْعَرْشِ الْكَـرِيْمِ

There is none worthy of worship but Allah the Mighty, the Forbearing. There is none worthy of worship but Allah, Lord of the Magnificent Throne. There is none worthy of worship but Allah, Lord of the heavens and Lord of the earth, and Lord of the Noble Throne.

[Sahih Bukhari – 6346]

اَللّٰهُـمَّ رَحْمَتَـكَ أَرْجُوْ فَلَا تَكِلـنِيْ اِلٰى نَفْـسِيْ طَـرْفَةَ عَـيْنٍ، وَّأَصْلِـحْ لِيْ شَاْنِيْ كُلَّـهٗ لَآ إِلٰهَ إِلَّآ اَنْـتَ

O Allah, I hope for Your mercy. Do not leave me to myself even for the blinking of an eye (i.e. a moment) and rectify for me all of my affairs. There is none worthy of worship but You.

[Sunan Abu Dawud – 5090]

اَللهُ اَللهُ رَبِّیْ لَآ أُشْـرِكُ بِهٖ شَيْـئًا

Allah, Allah is my Lord. I do not associate anything with Him.

[Sunan Abu Dawud – 1525]
