Jami` at-Tirmidhi Book 48, Hadith 216
“The best of supplication is the supplication of the Day of `Arafah. And the best of what I and the Prophets before me have said is: None has the right to be worshipped but Allah, Alone, without partner, to Him belongs all that exists, and to Him belongs the Praise, and He is powerful over all things. (Lā ilāha illallāh, waḥdahu lā sharīka lahu, lahul-mulku wa lahul-ḥamdu, wa huwa `alā kulli shai’in qadīr).’”
“O Allah, You are my `Aḍud and You are my Helper, and by You do I fight (Allāhumma anta `aḍudī, wa anta naṣīrī, wa bika uqātil).”
“The Messenger of Allah (ﷺ) taught me, saying: ‘Say: “O Allah, make my secret better than my apparent condition, and make my apparent condition righteous. O Allah, I ask You for the righteous of what you give to the people, of wealth, wives, and children, not (to be) misguided, nor misguiding. (Allāhummaj`al sarīratī khairan min `alāniyatī waj`al `alāniyatī ṣāliha. Allāhumma innī as’aluka min ṣālihi mā tu’tin-nāsa minal-māli wal-ahli wal waladi, ghairaḍ-ḍāli wa lal-muḍil).”
