Jami` at-Tirmidhi Hadith 479

Allah's Messenger (ﷺ) said: "Whoever has a need from Allah, or from one of the sons of Adam, then let him perform Wudu', performing it well, then pray two Rak`ah, then praise Allah and say Salat upon the Prophet (ﷺ). Then let him say: (La ilaha illallah Al-Halimul-Karim. Subhan Allah Rabbil-`Arshil-`Azim. Al-Hamdulillahi Rabbil-`Alamin. As'aluka mujibati rahmatika wa `aza'im maghfiratika, wal-ghanimata min kulli birrin, was-salamata min kulli ithmin, la tada` li dhanban illa ghafartahu, wa la hamman illa farrajtahu, wa la Hajatan hiya laka ridan Illa Qadaitaha, ya arham ar-rahimin) 'None has the right to be worshiped but Allah. Al-Halim (the Forbearing) Al-Karim (the Generous). Glorious is Allah, Lord of the Magnificent Throne. All praise is due to Allah, Lord of the worlds. I ask You for that which warrants Your mercy, and that which will determine Your forgiveness, and the spoils (fruits) of every righteous deed, and safety from every sin; do not leave a sin for me without forgiving it, nor a worry without relieving it. Or a need that pleases you without granting it. O Most-Merciful of those who have mercy.'"
