For one in distress

Lā ilāha illallāh al-`Aẓīmul-Ḥalīm, lā ilāha illallāh Rabbu ‘l-`Arshi ‘l-'Aẓīm, lā ilāha illallāh Rabbus-samāwāti wa Rabbu ‘l-arḍ wa Rabbu ‘l-`Arshi ‘l-Karīm.

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.

[ Al-Bukhari 8/154, Muslim 4/2092. Hisn al-Muslim 122 ]

Allāhumma raḥmataka arjū falā takilnī ilā nafsī ṭarfata `ayn, wa aṣliḥ lī sha'nī kullah, lā ilāha illā ant.

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

[ Abu Dawud 4/324, Ahmad 5/42. Al-Albani graded it as good in Sahih Abu Dawud 3/959. Hisn al-Muslim 123 ]

Lā ilāha illā anta subḥānaka innī kuntu minaẓ-ẓālimīn.

There is none worthy of worship but You, glory is to You. Surely, I was among the wrongdoers.

[ At-Tirmidhi 5/529. Al-Hakim declared it authentic and Ath-Thahabi agreed with him 1/ 505. See also Al-Albani, Sahih At-Tirmidhi 3/168. Hisn al-Muslim 124 ]

Allāh, Allāhu Rabbī lā ushriku bihi shay'a.

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